+		Sane Hotplug network interface management
+		-----------------------------------------
+
+INTRODUCTION
+------------
+	In the old day, all Wireless cards were managed by the
+excellent Pcmcia subsystem and its rich configuration scripts, and
+life was happy. Then came the wireless PCI cards, then the wireless
+USB dongles. Some unification was needed, and rather than adapt the
+Pcmcia subsystem for PCI and USB, it was decided to create the much
+simpler Hotplug systems.
+	The USB subsystem already use Hotplug, and the Pcmcia
+subsystem is migrating to it, CardBus cards (32 bits) already use
+Hotplug, whereas Pcmcia cards (16 bits) still use the old Pcmcia
+scripts.
+	The Hotplug system is still in its infancy, but already show
+some good promises. Most users are disapointed at first by its
+apparent lack of features compared to the Pcmcia scripts. In this
+document, we will show how to fully exploit the Hotplug system and try
+to implement the equivalent of all the functionality of the Pcmcia
+scripts.
+
+ASSUMPTIONS
+-----------
+	The target audience of this document is mostly power users and
+distribution maintainers, but it should give enough clues to help
+newbies. You should have read and understood DISTRIBUTIONS.txt. The
+procedures described here are more advanced than the simple
+configuration described in DISTRIBUTIONS.txt.
+	The main focus is of course removable wireless interfaces, but
+we will try to keep things generic and talk of the whole network
+interface management, so this should apply also to built-in Ethernet
+cards.
+
+PROBLEM STATEMENT
+-----------------
+	Let assume a Linux system and two or more network devices,
+Device A and Device B. Those devices may be built-in or removable,
+they may be present or absent from the system at any time, and
+activated in any particular order.
+	The user wants to assign Configuration A to Device A and
+Configuration B to Device B, without the possibility that Device A get
+assigned Configuration B.
+	Different users may have different definition of what is
+Device A. For some, it's a specific instance of a specific hardware,
+for others any hardware that meet some criteria (a wireless card, an
+Ethernet card).
+	The user may also want to have multiple configurations
+depending on various factors (like the old Pcmcia schemes). Device A
+may get Configuration A1 or Configuration A2 depending on those
+factors.
+	By default, all network interfaces are created using a default
+interface name (starting at "eth0" and going up). I call that problem
+"all my cards are eth0". And by default, "eth0" point to a single
+fixed configuration in the configuration database. Clearly, this won't
+satisfy our requirements.
+
+EXAMPLE SYSTEM
+--------------
+	The distribution I use is Debian 3.0, and some parts will be
+specific to it. However, it should be easy to translate to other
+distributions and I welcome additions to this document.
+
+	The example system is as follows :
+		o Linux 2.6.X SMP kernel with hotplug support
+		o Fully modular system (all network drivers as modules)
+		o PCI Ethernet card : AMD PCnet LANCE (pcnet32 - eth4)
+		o PCI Ethernet card : HP 100VG J2585B (hp100 - eth2)
+		o ISA Wireless card : Old AT&T Wavelan (wavelan - eth3)
+		o ISA-Pcmcia bridge : VADEM VG-469 (i82365 - slot 0)
+		o PCI-CardBus bridge : Ricoh RL5c475 (yenta_socket - slot 2)
+		o Pcmcia 802.11 card : Aironet 350 (airo_cs - eth0)
+		o Pcmcia 802.11 card : Lucent Orinoco (orinoco_cs - eth0)
+		o CardBus 802.11 card : SMC 2835W (prism54 - prism0)
+
+	This system just happen to be my Linux development box, and
+has enough interfaces to make it interesting. All the example I quote
+in this document are extracted from this fully working system.
+
+BASIC CONCEPTS
+--------------
+	Most of the concept and tricks presented here are not really
+new, the main contribution is to integrate them together and make them
+work.
+
+	1) Removable network interfaces are managed by Hotplug
+(Pcmcia, CardBus, USB...). We can't assume that those interfaces are
+always present in this system and available at boot time (Pcmcia cards
+are not made to be soldered in the Pcmcia slot), therefore Hotplug is
+the only way to go.
+	2) Built-in PCI and ISA cards are managed by the init scripts,
+like they have always been. The ISA subsystem will never have Hotplug
+support, and hotplug is not necessary for PCI cards.
+	3) Built-in devices that are disable most of the time should
+be enabled manually.
+	4) (1), (2) and (3) must be compatible on the same system and
+play nice with each other.
+
+	5) A well defined and consistent network interface name is
+assigned to each network hardware interface using 'ifrename'. Device A
+is always named 'ethA' (or whatever name you like such as
+'mynetworkcard').
+	6) No interface is called 'eth0' (or 'wlan0'). Any unknown
+device would be 'eth0', thefore known device should avoid using it
+because it might be already taken.
+	7) Multiple configurations for a single interface (schemes)
+are managed by the ifup/ifdown subsystem.
+
+CONFIGURATION FROM INIT SCRIPTS
+-------------------------------
+	It may seems paradoxal, but before setting up Hotplug, we need
+to make sure that the initialisation of network cards via init
+scripts is done properly and doesn't get in our way.
+	The configuration of network cards via init scripts is the
+traditional way network is initialised in Linux. The advantage of this
+method is that it's very well documented and understood, and has not
+changed much over the years. Unfortunately, it doesn't support
+properly removable cards.
+	The init scripts perform the following 3 functions in that
+order :
+		1) load necessary driver modules
+		2) rename interface to name chosen by the user
+		3) configure those interfaces
+
+	1) Applicability
+	----------------
+	Configuration from init scripts is applicable to any built-in
+network interface (ISA, PCI...), i.e. interfaces availalble at boot
+time and that will never be removed from the system.
+	The Hotplug subsystem has also the ability to configure some
+of the built-in network interfaces, such as PCI cards. However, there
+is a class of devices that will never have Hotplug support, such as
+ISA and EISA cards, and for those Hotplug won't work.
+	The advantage of using the init script method is that you are
+probably already familiar with it and you have the ability to select
+which interfaces should be configured at boot and which interface
+should only be enabled manually (whereas Hotplug just configures
+everything).
+
+	2) Loading driver modules (if/as needed)
+	----------------------------------------
+	Most distributions build the kernel drivers as modules. This
+modular setup allow to minimise the amount of memory used by the
+system and the flexible loading/unloading of drivers.
+	You can also compile your kernel with static drivers
+(non-modular). In that case, the driver will always be available in
+your kernel, you don't need to configure the module subsystem, so you
+can skip directly to the next section.
+
+	There are 3 alternatives to manage device drivers as
+modules. Some distribution have explicit list of modules that are
+loaded at boot time, if you want to use that feature you need to check
+your distribution. Some system, such as hotplug or kudzu, can scan the
+various buses of the PC and load the appropriate drivers, and this is
+mostly configuration-free, but may not support all devices. The module
+subsystem also allow to load modules 'on-demand'.
+
+	I personally prefer to use the 'on-demand' feature of the
+module subsystem has, as it allows you to not have to specify the list
+of modules that need to be loaded, and only modules really necessary
+are loaded which save kernel memory. You can also choose which module
+to load when there are multiple altenate modules valid for your
+hardware (which happens quite often).
+
+	With kernel 2.6.X, the module subsystem is configured in
+/etc/modprobe.conf. To configure 'on-demand' module loading, I need to
+add to this file the following lines :
+
+--------- /etc/modprobe.conf ----------------
+# HP 100VG J2585B PCI card
+alias eth2 hp100
+
+# AMD AMD PCnet LANCE PCI card
+alias eth4 pcnet32
+
+# Old AT&T Wavelan ISA card
+alias eth3 wavelan
+options wavelan io=0x390 irq=15
+---------------------------------------------
+
+	Your distribution may already have lines for your interfaces,
+either replace them or make sure they are correct (some distro are
+notorious for picking the wrong driver name). This file also contains
+configuration for lot of other subsystems, obviously you don't want to
+touch that.
+	In this file, you put the name you would like the interface to
+have (we'll fix that in a minute). You note that for modern PCI cards,
+this is much more straightforward than for old ISA cards.
+
+	3) Installing 'ifrename'
+	------------------------
+	You will need to install ifrename on your system. 'ifrename'
+is part of the Wireless Tools package (version 27 and later) and is a
+complete rewrite of the now obsolete 'nameif'.
+	Some distributions, such as Debian Sarge, offer a specific
+package for 'ifrename', and in this case you should just install this
+package. Other distributions may include ifrename as part of their
+'wireless tools' package (this should be the case for Geentoo and
+Mandrake). Other distributions, such as Debian 3.0, don't include
+ifrename at all, and you should compile yourself a recent version of
+Wireless Tools (v27 or later) and install it.
+
+	In any case, you should verify if 'ifrename' is properly
+installed, and what is the path to call it.
+--------------------------
+> which ifrename
+/sbin/ifrename
+--------------------------
+	Most distributions will install 'ifrename' in '/sbin', while if
+you compile your own wireless tools, it will be in '/usr/local/sbin'.
+
+	4) Making the boot scripts call 'ifrename'
+	------------------------------------------
+	You need to make sure 'ifrename' is run at boot time. Most
+distributions don't do that yet by default.
+	This is a part that is distribution specific, so you will need
+to look into your init files. It will need to run just before the call
+to 'ifup' or 'ifconfig' command.
+
+	In Debian 3.0, it needs to be run from /etc/init.d/networking,
+which is not the default. The necessary patch is below :

+----------------------------------------------------------------
+	Don't forget to set the appropriate path to call ifrename (see
+step (3) above).
+
+	You may want to also set the proper options for ifrename
+(check the man page).
+	The option '-p' enable module autoloading compatibility.
+	The default version of 'ifrename' also includes some specific
+Debian support : using "ifrename -p -d", only the proper modules are
+loaded. If you are using Debian, you should use this option.
+
+	5) Renaming interfaces
+	----------------------
+	As stated above, we use 'ifrename' to assign names to
+interfaces.
+
+	First, you need to get the MAC address of each of you
+interface. You can read it on the label on the card or display it
+using the 'ifconfig' command. Remember that the interface won't load
+yet with the proper name, so you may need to do a bit looking around :
+
+-----------------------------
+> modprobe pcnet32
+> ifconfig eth0
+eth0      Link encap:Ethernet  HWaddr 00:10:83:34:BA:E5  
+[...]
+-----------------------------
+
+	The configuration of 'ifrename' is simple, you just specify
+which name should be used for each MAC address in the file
+/etc/iftab :
+
+--------- /etc/iftab ------------------------
+# HP 100VG J2585B PCI card
+eth2		mac 08:00:09:*
+
+# Old AT&T Wavelan ISA card
+eth3		mac 08:00:0E:*
+
+# AMD AMD PCnet LANCE PCI card
+eth4		mac 00:10:83:*
+---------------------------------------------
+
+	The '*' in the MAC address is a wildcard and allow me to
+replicate my configuration between multiple identical computers. If
+you have to manage large number of computers (like a rack of server or
+clusters), you may want to look at other selectors offered by
+'ifrename', such as the ability to base interface name on Bus
+Information.
+
+	To test that ifrename works, do the following :
+		o load all your drivers, see section (2)
+		o check /proc/net/dev to see which interface exist
+		o bring all interfaces down : ifconfig ethX down
+		o run ifrename
+		o check each interface with ifconfig
+
+	6) Configuring interfaces
+	-------------------------
+	Most likely, your distribution is already doing this part
+properly. Just assign the proper IP and wireless configuration to each
+of the interface name you have chosen.
+	This part is distribution specific, and I already document it
+in the file DISTRIBUTIONS.txt.
+
+	In Debian, you would need to modify the file
+/etc/network/interfaces like this :
+
+--------- /etc/network/interfaces -----------
+# AMD AMD PCnet LANCE PCI card
+auto eth4
+iface eth4 inet dhcp
+
+# HP 100VG J2585B PCI card
+auto eth2
+iface eth2 inet static
+    address 10.0.0.2
+    network 10.0.0.0
+    netmask 255.255.255.0
+    broadcast 10.0.0.255
+    gateway 10.0.0.1
+---------------------------------------------
+
+	This was the last part. Now, at your next boot, all your
+interfaces should be assigned the proper name and proper
+configuration.
+
+CONFIGURATION VIA HOTPLUG
+-------------------------
+	Dealing with removable interfaces is similar to built-in
+interfaces, the only difference is that we will use the Hotplug
+scripts instead of the init scripts. Another difference is that it
+will require more work on your part because most distributions are not
+fully ready for it.
+
+	1) Applicability
+	----------------
+	The Hotplug configuration method is the best choice for any
+removable network interface, such as :
+		o Pcmcia (16 bits) network cards
+		o CardBus (32 bits) network cards
+		o USB network dongles
+		o Hot-PCI network cards
+	It may also be used to manage other types of network
+interfaces, although it may not be the best choice for them.
+
+	2) How Hotplug works
+	--------------------
+	Conceptually, Hotplug is very simple. When something
+interesting happens, the Linux kernel generates an Hotplug event. This
+run the proper script from the /etc/hotplug directory.
+	There is 3 types of Hotplug events we care about :
+		o PCI event : a CardBus device is added or removed
+from the system. The script /etc/hotplug/pci.agent is run.
+		o USB event : a USB device is added or removed
+from the system. The script /etc/hotplug/usb.agent is run.
+		o Network event : a network interface is added or
+removed from the system. The script /etc/hotplug/net.agent is run.
+
+	If we insert a CardBus network card in the system, the
+following happens :
+		1) Kernel detects new CardBus device
+		2) Kernel generates PCI Hotplug event
+		3) /etc/hotplug/pci.agent runs, find proper driver module
+		4) /etc/hotplug/pci.agent loads driver module
+		5) Driver module initialises, creates new network device
+		6) Kernel detects new network device
+		7) Kernel generates Network Hotplug event
+		8) /etc/hotplug/net.agent runs, configure network device
+	The sequence of events is similar for removals and USB devices.
+
+	3) Make ifup reentrant
+	----------------------
+	<Most people should ignore this part>
+	The first problem is that we need to make sure the command
+'ifup' is fully reentrant. If the system has built-in interfaces, the
+'ifup' may reenter itself at boot time :
+		1) Init scripts start running
+		2) Init script calls 'ifup -a' to initialise built-in network
+			interfaces
+		3) 'ifup' auto-loads driver module for built-in network
+			interface 'eth4'
+		4) Driver module initialises, creates new network device
+		5) Kernel generates Network hotplug event
+		6) /etc/hotplug/net.agent runs, call 'ifup eth4'
+	You can produce the same reentrancy if want to manually load
+module with the ifup command.
+
+	The default version of 'ifup' for Debian 3.0 is not reentrant and
+may deadlock during boot or if you use it manually. The patch to make
+'ifup' properly reentrant is available here :
+		http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=231197
+	Later version of Debian (Sarge and later) have some workaround
+that prevent deadlock in most case (but not fully eliminate them), so
+for normal use the default 'ifup' should work fine.
+
+	Other distributions have very different version of ifup, and I
+have not tried those (tell me about it).
+
+	4) Installing Hotplug for Debian Sarge (testing/unstable)
+	---------------------------------------------------------
+	Thanks to the great work of many people, Debian Sarge has all
+the necessary packages and hotplug support, and will work mostly 'out
+of the box'.
+	You will need to install the following packages :
+		o hotplug
+		o ifrename
+
+	While the installation of Hotplug is simple, its configuration
+may seem complex. The current network Hotplug script has 3 modes,
+'all', 'auto' and 'hotplug', however for our purpose they all produce
+the same results when configured. This is controlled by the variable
+NET_AGENT_POLICY in /etc/default/hotplug.
+
+	In the mode "all", all interfaces are processed by
+'ifup'. This will work without further configuration.
+
+	In the mode "auto", only interfaces listed in a auto statement
+in /etc/network/interfaces will be processed by 'ifup'. If you choose
+this mode, you need to put in /etc/network/interfaces a statement auto
+with the complete list of all interfaces.
+--------- /etc/network/interfaces -----------
+# Enable Hotplug support for "auto" mode (Sarge and later)
+auto eth0 eth1 eth2 eth3 eth4 wlan0 wlan1 prism0 prism1 airo0 airo1
+---------------------------------------------
+	Unfortunately, this will make 'ifup' complain at boot time
+that it can't find those interfaces. This is why I don't recommend
+this mode.
+
+	In the mode "hotplug", hotplug network events are ignored by
+ifup by default. To enable them, therefore making this mode equal to
+"all", you will need to add the following lines to
+/etc/network/interfaces :
+--------- /etc/network/interfaces -----------
+# Enable Hotplug support for "hotplug" mode (Sarge and later)
+mapping hotplug
+    script echo
+---------------------------------------------
+
+	5) Installing Hotplug for Debian 3.0
+	------------------------------------
+	Debian 3.0 doesn't come by default with hotplug, but the
+hotplug package is available as regular Debian package (on the CD or
+downloadable via apt-get), so you can just install that.
+
+	Unfortunately, this version of hotplug is not fully compatible
+with kernel 2.6.X. You will need to do the following modifications to
+the file /etc/hotplug/net.agent.
+
+------- /etc/hotplug/net.agent ------------------
+--- net.agent-d1        Fri Feb 20 18:18:05 2004

+     # ifstate database otherwise.
+-------------------------------------------------
+
+	Compared to the version in Sarge, this older version of
+hotplug is much more basic, and doesn't have any scanning at boot time
+and doesn't need to be enabled in /etc/network/interfaces.
+
+	6) Installing hotplug, other cases
+	----------------------------------
+	The canonical version of hotplug is available at :
+		http://linux-hotplug.sourceforge.net/
+
+	Most distributions have various version of hotplug with
+various modifications on top of the canonical version, and chances are
+that the canonical version won't completely work on your system.
+	All these various changing versions make it difficult for me
+to tell what exactly need to be changed in the hotplug scripts to make
+them work.
+
+	Some version of hotplug will do scan at boot time, see section
+(4) for my comments on this.
+
+	My guess is that in a few release, all these problems will
+sort themselves out. Just be patient.
+
+	7) Dealing with 'init' hotplug
+	------------------------------
+	In addition to the standard kernel Hotplug events, modern
+versions of the Hotplug scripts add init scripts that scan the system
+buses and generate pseudo Hotplug events. For the PCI buses, the
+script /etc/hotplug/pci.rc is run after the boot, for the USB bus,
+/etc/hotplug/usb.rc is run.
+	The end result is that the Hotplug subsystem will also attempt
+to configure built-in devices :
+		1) Kernel boots
+		2) Init runs, start to initialise the OS
+		3) /etc/hotplug/pci.rc runs, generate pseudo Hotplug event
+		4) /etc/hotplug/pci.agent loads driver module
+		5) Driver module initialises, creates new network device
+		6) Kernel generates Network Hotplug event
+		7) /etc/hotplug/net.agent runs, configure network device
+
+	At this point, you realise that at initialisation, both
+Hotplug and the regular init scripts (see "CONFIGURATION FROM INIT
+SCRIPTS") are trying to configure the same devices in parallel. This
+may create problem, and it is totally redundant.
+	Another reason I don't like this mechanism is that it blindly
+attempt to load drivers for all hardware present on the system, and
+don't use the configuration in /etc/modules.conf to select the proper
+driver. It's fairly common to have multiple driver for some hardware,
+and because of Murphy's law, Hotplug will usually load the wrong
+one. It's also fairly common to have hardware on the system that
+doesn't need enabling (for example, the IDE controller on my SCSI
+machine), not loading the driver makes your kernel smaller and boot
+faster.
+	Unfortunately, Hotplug did not provide a simple way to disable
+such a feature. More importantly, there is no way to selectively
+disable it (let say, disabled for network, enabled for sound).
+
+	One way to disable this functionality is to delete or rename
+the files /etc/hotplug/pci.rc and /etc/hotplug/usb.rc.
+
+	8) Making hotplug scripts call ifrename
+	---------------------------------------
+	The last hotplug step is to make sure that 'ifrename' is run
+by the hotplug subsystem at the right time. As before, we want to run
+it just before calling 'ifup'.
+	The latest version of the hotplug scripts have this
+integrated. However, you need to check that the path they use for
+calling 'ifrename' is the proper one on your system. And, for older
+versions of hotplug scripts, you will need to add this support
+yourself.
+
+	Check the path for ifrename :
+--------------------------
+> which ifrename
+/sbin/ifrename
+--------------------------
+
+	The patch to add 'ifrename' to hotplug looks like :
+
+------- /etc/hotplug/net.agent ------------------
+--- net.agent-s2        Fri Feb 20 17:18:46 2004

+
+	If your hotplug scrips already include ifrename support, you
+should find a section in /etc/hotplug/net.agent looking like the patch
+above. Otherwise, just cut'n'paste the patch above in the right place.
+	The path for 'ifrename' is used twice above, so don't forget
+to modify both occurences...
+
+
+	9) Loading driver modules
+	-------------------------
+	Wow ! The most difficult part is done.
+	In theory, you don't need to do any specific configuration for
+the driver modules to be loaded. The 'pci.agent' and 'usb.agent'
+should load the right driver module for you.
+	Also, you don't need to define aliases in /etc/modprobe.conf,
+it's useless (and may be counter productive).
+
+	If you use driver compiled statically in the kernel, you also
+have nothing to do.
+
+	10) Renaming interfaces
+	-----------------------
+	We still use ifrename to assign names to interfaces. The
+configuration of 'ifrename' is the same. To keep the possibility of
+having multiple wireless cards (one in each CardBus slot), we use
+wildcards in both the MAC address and the name :
+
+--------- /etc/iftab -----------------------
+# SMC 2835W wireless CardBus card
+prism*		mac 00:30:B4:*
+---------------------------------------------
+
+	If you insert two cards, they would be named prism0 and
+prism1. Note that 'name wildcarding' is a feature only available in
+2.6.X, so if you use 2.4.X you will need to be explicit and list each
+card separatly :
+
+--------- /etc/iftab -----------------------
+# SMC 2835W wireless CardBus card
+prism0		mac 00:30:B4:64:27:8B
+prism1		mac 00:30:B4:64:27:8D
+---------------------------------------------
+
+	11) Configuring interfaces
+	-------------------------
+	At this point, configuration of Hotplug interfaces is done
+just like their built-in counterparts. This part is still distribution
+specific, and still already document in the file DISTRIBUTIONS.txt..
+
+	In Debian, you would need to modify the file
+/etc/network/interfaces like this :
+
+--------- /etc/network/interfaces -----------
+# Enable Hotplug support (Sarge and later)
+mapping hotplug
+    script echo
+
+# SMC 2835W wireless CardBus card
+iface prism0 inet static
+    address 10.0.1.2
+    network 10.0.1.0
+    netmask 255.255.255.0
+    broadcast 10.0.1.255
+    wireless-essid THE_ESSID
+    wireless-mode ad-hoc
+    wireless-channel 5
+---------------------------------------------
+
+	Now, just cross your finger and plug the card in the slot...
+
+PCMCIA INTERFACES (16 bits)
+---------------------------
+	The Pcmcia subsystem has quite some legacy, and can use
+various configuration procedure. The Pcmcia subsystem fully use
+hotplug for 32 bits card (if you are using the kernel Pcmcia modules,
+which is the only option for 2.6.X). For 16 bits cards, we can't make
+them fully hotplug yet and need the cardmgr and /etc/pcmcia directory,
+however we can make their network configuration use hotplug.
+
+	To use Hotplug network configuration with 16 bits Pcmcia
+cards, first make sure the Pcmcia subsystem is properly configured and
+that cardmgr load the right module (in most case, it should). Then,
+make sure that you don't have any configuration entries in
+/etc/pcmcia/network.opts and /etc/pcmcia/wireless.opts. Make sure that
+none of entries in your system network configuration use 'eth0' or
+'wlan0' (in /etc/network/interfaces for Debian users).
+	Then, just follow the procedure described above for
+"Configuration Using Hotplug" to configure your network cards.
+
+	You might want a little bit of explanation on why this magic
+will work (which would help in case it doesn't work).
+	There is two types of Pcmcia network configuration scripts,
+available as /etc/pcmcia/network. The original Pcmcia script configure
+network cards using options found in /etc/pcmcia/network.opts and
+/etc/pcmcia/wireless.opts. Most distributions replace it with a script
+calling 'ifup'. By making sure that network.opts and wireless.opts are
+"empty", we neutralise the first set of scripts. By making sure no
+system configuration uses 'eth0' or 'wlan0', we neutralise the second
+set of scripts, the script would call 'ifup' with the default
+interface name, which is usually 'eth0', ifup would not find a
+configuration for it and would just ignores it.
+	The card would still be configured because hotplug network
+events are generated for every interfaces, not only for devices
+managed by hotplug. So, net.agent would receive an event and perform
+the necessary steps to configure it.
+
+	Personally, I'm still using the original Pcmcia scripts for my
+Pcmcia cards as described in the file PCMCIA.txt, because I will
+migrate my complex configurations over time.
+	You can also decide to not use Hotplug for Pcmcia cards and
+modify the distribution Pcmcia scripts in /etc/pcmcia/* to handle
+Pcmcia cards properly. You would need to modify /etc/pcmcia/network to
+add 'ifrename' before 'ifup' the same way it was done for
+/etc/hotplug/net.agent. But, as in the long term Pcmcia will migrate
+to Hotplug, I would not bother...
+
+MANUAL LOADING, DOCKING STATIONS
+--------------------------------
+	Manual loading is used for built-in network interfaces that
+are only use at specific time, and that you want disabled the rest of
+the time. We assume that you still use modules so that when the
+interface is not used you can remove the driver from the kernel.
+
+	First, you need to set the configuration for those interfaces,
+the same way it's done for other network interfaces. The main
+difference is that you need to specify that those interfaces should
+not be enabled at boot time. It's also a good idea to disable Hotplug
+init scripts.
+	With Debian, you just need to make sure that the 'auto"
+keyword doesn't apply to this interface.
+--------- /etc/network/interfaces -----------
+# AMD AMD PCnet LANCE PCI card
+iface eth4 inet dhcp
+---------------------------------------------
+
+	If you use driver statically built in the kernel, you can just
+enable and disable those interfaces with 'ifup ethX' and 'ifdown ethX'.
+
+	If you use both a modular system and 'ifrename', you will need
+to change your habits when enabling those devices. The classical 'ifup
+ethX' won't work.
+	If you don't use Hotplug, you need to do :
+-----------------------------------
+modprobe eth4
+ifrename
+ifup eth4
+-----------------------------------
+	If you use hotplug, you only need to do :
+-----------------------------------
+modprobe eth4
+-----------------------------------
+
+	On the other hand, disabling the interface has not changed :
+-----------------------------------
+ifdown eth4
+modprobe -r eth4
+-----------------------------------
+	Using "modprobe -r" make sure that if the driver is composed
+of multiple module all the modules are unloaded.
+
+	Docking stations for laptops may contain built-in
+interfaces. My previous laptop had one, and Linux had no support for
+it. To be able to simply manage my docking station, I had created two
+little scripts to enable and disable my network interface.
+	After docking, you would run :
+-------- /sbin/dock ----------------------------
+#!/bin/sh
+modprobe eth4
+ifrename
+ifup eth4
+------------------------------------------------
+	And prior to undocking, you would run :
+-------- /sbin/undock ----------------------------
+#!/bin/sh
+ifdown eth4
+modprobe -r eth4
+------------------------------------------------
+	Thanks to 'ifrename', the network interface in your dock will
+always be properly configured regardless of if you have a Pcmcia
+network card in the Pcmcia slot or not.
+
+SCHEMES (MULTI-CONFIG)
+----------------------
+	Most Ethernet cards will only connect to a single network, or
+can use DHCP to be auto-configured. With Wireless Cards, it's much
+more likely that you will need multiple configurations, for example at
+work, at home and on-the-go.
+
+	Most distributions have various level of support for such
+schemes. Some distributions offer simple network schemes, while other
+offer "overall" schemes changing the whole configuration. I document
+the support for schemes in various distributions in the file
+DISTRIBUTIONS.txt.
+
+	You can also use tools such as IfPlugd, WapRoamd or
+Wlandetect. Those tools are a kind of "wireless-DHCP", they attempt to
+automatically detect the proper wireless configuration and apply
+it. Most will also attempt to detect network changes.
+	The main limitation of those tools is that they offer very
+little manual control. If two valid alternatives are possible, you
+can't switch between them. If a configuration can't be detected, they
+usually fail.
+	That's the same concept as using DHCP versus Static IP
+addresses. Some people are very happy with DHCP, my style is Static IP
+addresses.
+
+	If you use Debian and want to use simple manual schemes, these
+are the things you need to do.
+	1) Make sure that 'ifscheme' and 'ifscheme-mapping' are
+installed on the system. You may find them in a separate tar file on
+my web site.
+	2) Check the path for 'ifscheme-mapping' (using whereis).
+	3) Modify you /etc/network/interface to add proper mapping and
+configuration.

+
+FIRMWARE LOADING
+----------------
+	A lot of modern wireless card don't have built in firmware and
+need firmware loading. Recent kernel (2.6.X) have a firmware
+loader. These are a few notes on how to use it.
+
+	First, read the documentation coming with your driver, because
+each driver has specificities (like the name of the firmware file it
+requires).
+
+	You need to compile your kernel with firmware loading
+(CONFIG_FW_LOADER in "Generic Driver Options"). If your driver was
+built from the kernel, chances are that it enabled this feature
+already. Make sure you boot from this new kernel.
+
+	The 'sysfs' file system must be mounted. The easiest is to
+mount it at boot time, add a line for it in /etc/fstab :
+
+-------- /etc/fstab ------------------------------
+sysfs		/sys	      sysfs  defaults                   0      0
+--------------------------------------------------
+
+	Then, you add the firmware file in the directory where it's
+expected, which is /usr/lib/hotplug/firmware/ in most cases.
+
+	Most distributions nowadays have a version of the Hotplug
+scripts that knows how to deal with firmware. If it is not the case,
+just grab the 'firmware.agent' file from an alternate source and copy
+it into your /etc/hotplug directory (make sure it's executable).
+	You can try the canonical version :
+		http://linux-hotplug.sourceforge.net/
+	Or Debian's version :
+		http://packages.debian.org/unstable/admin/hotplug
+
+	Note that firmware loading will usually only work with
+interfaces that are fully managed by Hotplug. This is the only way to
+ensure the that proper sequence of action is happening in the right
+order every time. Firmware loading will usually not work properly for
+interfaces configured in the init scripts.
+	This means that if you have a built-in interface that require
+firmware loading, you should just use manage those interfaces like
+removable interfaces (see section above). However, interface
+configuration need to be explicitely triggered at boot time.
+
+	One possibility is to set-up Hotplug to be run from the init
+script at boot time. This is usually an option for recent
+distributions (it's not the case for Hotplug in Debian 3.0). But, we
+have seen that this has some issues.
+	The other possibility is to use an hybrid between the init
+script method and the hotplug method. First, you need to add an alias
+for the driver in /etc/modprobe.conf. Then, you need to specify a
+mapping for this interface in /etc/iftab, and specify a configuration
+for this interface and that that it is enabled at boot time. Lastly,
+you make sure that the network init scripts run 'ifrename
+-p'. 'Ifrename' will trigger the module to load, and all the Hotplug
+events will be generated properly to configure the interface.
+
+DEVICES WITH MULTIPLE NAMES
+---------------------------
+	Some wireless drivers offer multiple network interfaces for
+the same device. A classical example is the Aironet driver that
+creates a 'ethX' and 'wifiY' for each card.
+
+	'ifrename' allow you a finer selection of interfaces than
+'nameif'. For example, to only rename the pseudo-Ethernet network
+interface name of the Aironet driver, you would do :
+
+--------- /etc/iftab -----------------------
+# Cisco Aironet 350 wireless Pcmcia card
+airo*		mac 00:07:0E:* arp 1
+---------------------------------------------
+
+	After that, your device would be available through 'eth0' and
+'wifi0'.
+
+	You can rename both interfaces. You just need to remember that
+'ifrename' start matching from the last line of the file, so you would
+do :
+--------- /etc/iftab -----------------------
+# Cisco Aironet 350 wireless Pcmcia card
+wifi*		mac 00:07:0E:*
+airo*		mac 00:07:0E:* arp 1
+---------------------------------------------
+
+	The current version of 'ifrename' support only the most useful
+selectors, and is architectured such as adding selectors is relatively
+trivial. If you find a case that 'ifrename' can't handle, you should
+just extend it.
+
+DEVICES WITHOUT MAC ADDRESSES
+-----------------------------
+	Most Ethernet and Wireless devices have a fixed and unique MAC
+address, and it is therefore advised to name them based on this
+criteria. However, there is also network interfaces that don't have a
+fixed and unique MAC address, for example Ethernet over USB, IP over
+FireWire, PPP and tunnel interfaces.
+	The driver for those devices create the interface with a name
+specific to the driver, such as ppp* for PPP interfaces and usb* for
+Ethernet over USB, and therefore they are easy to identify and
+configure, and few users feel the need to rename them. Moreover, some
+of them, such as PPP, have their own configuration scripts and
+methodology addressing their unique needs.
+
+	There is a few cases where you might want to rename interfaces
+withour MAC addresses. One example is two Ethernet over USB
+dongles. The way to do this is to use alternate ifrename
+selectors. Choosing the right selector depend on what you want to
+achieve.
+	A quick theoretical example to illustrate :
+--------- /etc/iftab -----------------------
+# All other usbnet devices
+usb*		driver usbnet
+# Specific usbnet devices
+usb-p		firmware "Prolific PL-2301/PL-2302"
+usb-4		bus-info usb-00:02.0-1.4
+---------------------------------------------
+
+TROUBLESHOOTING
+---------------
+	If your interface doesn't show up as expected with ifconfig,
+you will need to find out why. First, you need to be familiar with the
+sequence of actions in the system and find which one did not happen.
+
+	You need to check if the driver module(s) was loaded using
+'lsmod'.
+
+	You need to check if the interface was properly renamed with
+'ifrename'. You can use 'ifrename -D -V' to debug your /etc/iftab.
+	Get the the list of interfaces on your system with 'cat
+/proc/net/dev', and check if an interface is using the name you
+assigned or 'eth0'. Check any suspicious interfaces with 'ifconfig
+eth0', and check its MAC address. Note that some rare drivers don't
+have a proper MAC address before brought up, which fools ifrename.
+	Verify that no line in /etc/iftab matches the all-zero MAC
+address. The all-zero MAC address matches the loopback interface 'lo'
+and various pseudo network devices, renaming the loopback interface is
+highly discouraged.
+
+	You need to check which configuration was given to the
+interface using 'ifconfig' and 'iwconfig'.
+
+	The Hotplug subsystem has also good debugging facilities.
+	To enable Hotplug debugging, just make sure the variable DEBUG
+is defined in /sbin/hotplug :
+--------- /sbin/hotplug ------------------------------
+--- /sbin/hotplug-old      Tue Mar 26 09:00:20 2002
++++ /sbin/hotplug       Fri Feb 20 18:40:38 2004

+------------------------------------------------------
+	Then, you can check your message logs for Hotplug events with
+'tail -f /var/log/messages'. Verify that the various Hotplug events
+happen as expected (pci, firmware, net...), and verify the log
+messages from 'net.agent'.

+	This release of the Wireless Tools is not compatible with

+but are not recommended. Version 8 and earlier will not work.
+	Kernels that support this version of the Wireless Tools are
+listed below. For all kernels before that, see at the end.
 
 You need :
 --------
 	o Compiler and development environment
-	o A kernel supporting wireless extensions version 9 or higher
-		-> from 2.2.14 onward
-		-> from 2.3.24 onward
+	o A kernel supporting wireless extensions version 11 or higher
+		-> from 2.4.4 onward (including 2.6.X)
 		Note : CONFIG_NET_RADIO must be enabled
 	o (Optional) A Pcmcia package supporting Wireless Extension
 	o A driver supporting wireless extensions
-		-> Check my web pages for latest list of drivers,
-			otherwise patch your favourite driver...
+		-> Check my web pages for status of various drivers.
 	Note : more recent kernels and drivers are likely to support
 		more wireless extension features...
 
 Compile wireless tools :
 ----------------------
 	In theory, a "make" should suffice to create the tools.
-	In practice, there is big troubles with the kernel
-headers. See below for how to fix that.
-	Note : as some internal data structures change from kernel to
-kernel, you are advised to not use the precompiled version of the
-tools but to recompile your own.
 
 Installation :
 ------------
-	If I were you, I would not trust a "make install". If you feel
-courageous, just do "make install". It may even do the right
-thing. Actually, with the various bugfixes that happened over the
-time, it nowadays tend to do the right thing.
-	I advise to copy the executable (iwconfig, iwspy and iwpriv)
-in /usr/local/sbin or /usr/sbin. The man pages (iwconfig.8, iwspy.8
-and iwpriv.8) should be copied in /usr/local/man/man8 or
-/usr/man/man8.
-	In fact, if you want to use Pcmcia wireless.opts, this step is
-mandatory...
+	"make install" should do the right thing for you, and install
+the tools, their library and the man pages. You can also uninstall the
+tools via "make uninstall".
+	Note that the default installation is in the directory
+'/usr/local/sbin'. This may not be in your path. Also, other version
+of the tools may exist on the system, so double check which version is
+the default and adjust your path as necessary.
 
-Kernel headers (why it doesn't compile) :
----------------------------------------
-	Some changes in the kernel headers and glibc headers are
-making my life difficult. We now have a mechanism to automatically
-select the proper header based on various bits of information (libc
-version & kernel version), but it may fail to do the right thing.
-	You may also see the message :
-		"Your kernel/libc combination is not supported"
-	If this happens to you, you will need to hack the rules at the
-top of iwlib.h and send me the patch.
-
-	The second issue is that some distributions install some
-independant kernel headers in /usr/include. If you upgrade your
-kernel, those headers become out of sync and you don't benefit from
-the latest Wireless Extensions. Even worse, it can sometimes prevent
-the tools from compiling.
-	The trick is to copy the file .../include/linux/wireless.h
-from the kernel to the /usr/include headers.
-
-Multi-kernel installation (expert only) :
----------------------------------------
-	People who run different kernel on the same system may have
-problems due to the fact that those kernel have different version of
-Wireless Extensions and the Wireless Tools need to match the version
-of Wireless Extension used.
+Create a local copy of the tools :
+--------------------------------
+	By default, the package is built with iwlib as a dynamic
+library, and the tool will expect to use the default version of libiw
+on the system.
+	If you just want to experiment with a "local" version of the
+tools, you may want to pass the BUILD_STATIC flag to Makefile. It will
+create a self contained version of the tools.
+-------------
+make clean
+make BUILD_STATIC='y'
+-------------
+	The resulting binary can be used in the compilation directory
+or installed in any place you like.
 
-	It is now possible to install multiple versions of the
-Wireless Tools on a system and get the proper version used based on
-the kernel running, using a redirector. However, this support is still
-experimental and for expert users only.
-	The redirector will work properly only with kernel using
-Wireless Extensions version 16 and higher. Earlier version of Wireless
-Extensions will be detected as either v15 (v12, v13, v14 and v15) or
-as v11 (v11 and earlier).
+Wireless headers (past history) :
+-------------------------------
+	Previous version of the Wireless Tools had to be compiled with
+the same version of Wireless Extension that the kernel was using, and
+that was a major source of troubles.
+	Starting with version 27, Wireless Tools include all the ugly
+code to deal with any version of Wireless Extensions, so now you can
+compile a single "generic" version of the tools for any kernel.
+	Well, there are some limits, Wireless Extensions earlier than
+v11 are not supported (v9 and v10 should work fine), and versions
+later than the latest definition in the package are not
+supported. Once compile, the command "iwconfig --version" should tell
+you that.
+	Note that the previous option to make versioned installed of
+the tools no longer make sense and therefore is gone.
 
-	The installation looks typically like :
-------------------------------------
-make clean
-make FORCE_WEXT_VERSION=11
-make vinstall FORCE_WEXT_VERSION=11
-make clean
-make FORCE_WEXT_VERSION=15
-make vinstall FORCE_WEXT_VERSION=15
-make clean
-make FORCE_WEXT_VERSION=16
-make vinstall FORCE_WEXT_VERSION=16
-[...]
-------------------------------------
+Other useful Makefile options :
+-----------------------------
+	PREFIX : where the tools will be installed (default : /usr/local)
+	BUILD_STATIC : build tools with a static version of the wireless lib
+	BUILD_NOLIBM : build tools without mathematical lib (slower)
+	Note that you should pass the same command line options for
+all invocations of make ("make" and "make install").
 
+Old kernel with older Wireless Extensions :
+-----------------------------------------
+	Kernel prior to 2.2.14 : Those kernels include Wireless
+Extensions v8 or earlier. Those versions don't have proper support for
+802.11b, so are not very useful. You may want to consider upgrading.
+	Kernel 2.2.19 to 2.2.25 : Those kernels include Wireless
+Extensions v10. The tools should mostly work with it, but many drivers
+won't. You can upgrade those kernel to WE v15 with a patch on my web
+page.
+	Kernel 2.2.14 to 2.2.18 : Those kernels include Wireless
+Extensions v9. Same as above, you may want to upgrade to a later 2.2.X
+kernel and then apply the patch.
+	Kernel 2.0.X : Those kernels include very old version of
+Wireless Extensions. Same deal as old 2.2.X kernels.

+.\" DESCRIPTION part

+.SH DESCRIPTION
+.B Ifrename
+est un outil vous permettant d'assigner un nom cohérent à chacune de vos
+interfaces réseau.
+.PP
+Par défaut, les noms d'interface sont dynamiques, et à chaque interface réseau
+est assigné le premier nom disponible
+.RI ( eth0 ", " eth1 "...)."
+L'ordre dans lequel les interfaces réseau sont créées peut varier. Pour les
+interfaces fixes («\ built-in interfaces\ »), l'énumération du noyau au
+démarrage peut varier. Pour les interfaces débranchables, l'utilisateur peut les
+brancher dans n'importe quel ordre.
+.PP
+.B Ifrename
+permet à l'utilisateur de décider quel nom une interface réseau aura.
+.B Ifrename 
+peut utiliser différents sélecteurs
+.RI "(«\ " selectors "\ »)"
+pour spécifier comment les noms d'interface correspondent aux interfaces réseau
+du système, le plus commun des sélecteurs étant
+.RI "l'" "adresse MAC"
+de l'interface.
+.PP
+.B Ifrename
+doit être lancé avant que les interfaces ne soient démarrées, raison pour
+laquelle il est surtout utile dans divers scripts (init, hotplug), mais il est
+rarement utilisé directement par l'utilisateur. Par défaut,
+.B ifrename 
+renomme toutes les interfaces système présentes en utilisant les correspondances
+définies dans
+.IR /etc/iftab .
+.\"
+.\" PARAMETER part
+.\"
+.SH PARAMÈTRES
+.TP
+.BI "-c " configfile
+Fixe le fichier de configuration à utiliser (par défaut
+.IR /etc/iftab ).
+Le fichier de configuration définit la correspondance entre les sélecteurs et
+les noms d'interface, et il est décrit dans
+.IR iftab (5).
+.br
+Si
+.I configfile
+est «\ -\ », la configuration est lue depuis stdin.
+.TP
+.B -p
+Sonde (charge) les modules noyau avant de renommer les interfaces. Par
+défaut,
+.B ifrename 
+vérifie seulement les interfaces déjà chargées, et ne charge pas
+automatiquement les modules noyau requis. Cette option autorise une intégration
+en douceur dans les systèmes qui ne chargent pas les modules avant d'appeler
+.BR ifrename .
+.TP
+.B -d
+Active divers bidouillages spécifiques à la
+.BR Debian .
+Combiné avec
+.BR -p ,
+seuls les modules pour les interfaces spécifiées dans
+.I /etc/network/interface
+sont chargés.
+.TP
+.BI "-i " interface
+Renomme seulement
+.RI "l'" interface 
+spécifiée, par opposition à toutes les interfaces présentes sur le système. Le
+nouveau nom de l'interface est affiché.
+.TP
+.BI "-n " newname
+Si utilisé avec
+.IR -i ,
+spécifie le nouveau nom de l'interface. La liste des correspondances depuis le
+fichier de configuration est ignorée. Le nouveau nom peut être un joker
+(«\ wildcard\ ») qui contient une seule '*'.
+.TP
+.B -t
+Active l'absorption («\ takover\ ») de nom. Cela permet d'échanger un nom
+d'interface entre deux interfaces ou plus.
+.br
+L'absorption permet à une interface de «\ voler\ » le nom d'une autre
+interface. Cela fonctionne seulement avec le noyau 2.6.X et si l'autre
+interface est désactivée. En conséquence, ce n'est pas compatible avec Hotplug.
+L'autre interface se voit assigner un nom aléatoire, mais peut être renommée
+plus tard avec 'ifrename'.
+.br
+Le nombre d'absorptions est limité pour éviter les boucles circulaires, et donc
+certaines situations d'échanges de noms complexes ne seront pas complètement
+traitées.
+.br
+Dans tous les cas, l'échange de noms et l'utilisation de cette caractéristique
+sont découragés, et vous êtes invités à choisir des noms uniques et sans
+ambiguïté pour vos interfaces...

+.SH CORRESPONDANCES («\ MAPPINGS\ »)
+Chaque correspondance est décrite sur une ligne distincte, elle commence avec
+.IR "interface name" " (nom d'interface),"
+et contient un ensemble de
+.RI "descripteurs («\ " descriptors "\ »),"
+séparés par des espaces ou des tabulations.
+.PP
+La relation entre les descripteurs d'une correspondance est un
+.IR "et logique" .
+Une correspondance s'applique à une interface réseau seulement si tous les
+descripteurs s'appliquent. Si une interface réseau ne supporte pas un
+descripteur particulier, elle ne s'appliquera à aucune correspondance qui
+utilise ce descripteur.
+.PP
+Si vous voulez utiliser des descripteurs alternatifs pour un nom d'interface
+(ou logique), spécifiez deux correspondances différentes avec le même nom
+d'interface (une par ligne).
+.B Ifrename
+utilise toujours la première correspondance en commençant par la

+de
+.BR iftab ,
+donc les correspondances les plus restrictives devraient être définies en
+dernier.
+.\"
+.\" INTERFACE NAME part

+interface réseau correspond à tous les descripteurs d'une correspondance,
+.B ifrename
+essaye de changer le nom de l'interface par le nom de l'interface donné dans la

+.PP
+Le nom de l'interface d'une correspondance est soit un nom d'interface complet
+(comme
+.IR eth2 " ou " wlan0 )
+ou un motif de nom d'interface contenant un seul caractère joker (comme
+.IR eth* " ou " wlan* ).
+Dans le cas d'un caractère joker («\ wildcard\ »), le noyau remplace le
+caractère '*' par le plus petit entier disponible faisant un nom d'interface
+unique.
+.\"
+.\" DESCRIPTORS part
+.\"
+.SH DESCRIPTEURS («\ DESCRIPTORS\ »)
+Chaque descripteur est composé d'un nom de descripteur et d'une valeur de
+descripteur. Les descripteurs définissent un attribut statique d'une interface
+réseau, le but étant d'identifier de manière unique chaque périphérique.
+.PP
+La plupart des utilisateurs n'utiliseront que le sélecteur
+.BR mac ,
+les autres sélecteurs étant pour une configuration plus spécialisée.
+.TP
+.BI mac " adresse mac"
+Correspond à l'Adresse MAC de l'interface avec l'adresse MAC spécifiée.
+L'adresse MAC de l'interface peut être montrée en utilisant
+.IR ifconfig (8)
+ou
+.IR ip (8).
+L'adresse MAC spécifiée peut contenir une '*' pour la correspondance joker
+(«\ wildcard matching\ »).
+.br
+C'est le plus commun des sélecteurs, vu que chaque interface possède une
+adresse MAC unique, ce qui permet de les identifier sans ambiguïté.
+.TP
+.BI arp " arp type"
+Fait correspondre le Type ARP («\ ARP Type\ ») (aussi appelé «\ Link Type\ »)
+de l'interface avec le type ARP spécifié. Le Type ARP de l'interface peut être
+montré en utilisant
+.IR ifconfig (8)
+ou
+.IR ip (8).
+.br
+Ce sélecteur est utile quand un pilote crée plusieurs interfaces réseau pour
+une seule carte réseau.
+.TP
+.BI driver " driver name"
+Fait correspondre le Nom de Pilote («\ Driver Name\ ») de l'interface avec le
+nom de pilote spécifié. Le Nom de Pilote de l'interface peut être montré en
+utilisant
+.IR "ethtool -i" (8).
+.TP
+.BI businfo " bus information"
+Fait correspondre l'Information de Bus («\ Bus Information\ ») de l'interface
+avec l'information de bus spécifiée. L'Information de Bus de l'interface peut
+être montrée en utilisant
+.IR "ethtool -i" (8).
+.TP
+.BI baseaddress " base address"
+Fait correspondre l'Adresse de Base («\ Base Address\ ») de l'interface avec
+l'adresse de base spécifiée. L'Adresse de Base de l'interface peut être montrée
+en utilisant
+.IR ifconfig (8).
+.br
+Ce sélecteur n'est utile que pour les cartes ISA et EISA car la plupart des

+.PP
+Tous ces paramètres et statistiques dépendent du matériel. Chaque pilote ne

+l'étendue des valeurs peut changer. Veuillez vous référer aux pages man de
+chaque matériel pour plus de détails.
+.\"
+.\" PARAMETER part
+.\"
+.SH PARAMÈTRES
+.TP
+.B essid
+Positionne le ESSID ( ou Network Name - pour certains produits, il peut aussi
+être désigné comme Domain ID). L'ESSID est utilisé pour identifier les cellules
+qui font partie du même réseau virtuel.
+.br
+Par opposition à l'adresse de l'AP ou au NWID qui définissent une seule cellule,
+l'ESSID définit un groupe de cellules connectées via des répéteurs ou via
+l'infrastructure, où l'utilisateur peut «\ roamer\ » ou errer de manière
+transprente (c.-à-d. changer de cellule sans perdre sa connexion).
+.br
+Avec certaines cartes, vous pouvez désactiver le contrôle du ESSID (ESSID
+promiscuous) avec
+.IR off " ou " any " (et " on
+pour le réactiver).
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 essid any"
+.br
+.I "	iwconfig eth0 essid ""Mon Reseau""
+.TP
+.BR nwid / domain
+Positionne le Network ID (pour certains produits, il peut aussi être appelé
+Domain ID). Comme tous les réseaux sans fil adjacents partagent le même médium,
+ce paramètre est utilisé pour les différencier (créer des réseaux logiques
+colocalisés) et pour identifier des noeuds appartenant à la même cellule.
+.br
+Ce paramètre est seulement utilisé par les matériels antérieurs à 802.11, la
+norme 802.11 se servant du ESSID et de l'adresse de l'AP pour cette fonction.
+.br
+Avec certaines cartes, vous pouvez désactiver le contrôle du Network ID (NWID
+promiscuous) avec
+.IR off " (et " on
+pour le réactiver).
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 nwid AB34
+.br
+.I "	iwconfig eth0 nwid off"
+.TP
+.BR freq / channel
+Positionne la fréquence d'exploitation ou canal du périphérique. Une valeur
+inférieure à 1\ 000 indique un numéro de canal, une valeur supérieure à 1\ 000
+est une fréquence en Hz. Vous pouvez ajouter le suffixe k, M ou G à la valeur
+(par exemple, «\ 2.46G\ » pour la fréquence 2,46\ GHz), ou ajouter suffisamment
+de «\ 0\ ».
+.br
+Les canaux sont habituellement numérotés à partir de 1, et vous pouvez utiliser
+.IR iwlist (8)
+pour obtenir le nombre total de canaux, lister les fréquences disponibles, et
+afficher le fréquence courante comme un canal.
+Suivants les réglementations, certaines fréquences/canaux peuvent ne pas
+être disponibles.
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 freq 2422000000"
+.br
+.I "	iwconfig eth0 freq 2.422G"
+.br
+.I "	iwconfig eth0 channel 3"
+.TP
+.B sens
+Positionne le seuil de sensibilité. C'est le niveau de signal le plus bas pour
+lequel le matériel essaye de réceptionner un paquet, les signaux plus bas sont
+ignorés. Ceci est utilisé pour éviter de recevoir le bruit de fond, donc vous
+devriez le positionner en fonction du niveau de bruit moyen. Les valeurs
+positives sont supposées être les valeurs brutes utilisées par le matériel ou
+un pourcentage, les valeurs négatives sont supposées être des dBm.
+.br
+Avec certains matériels, ce paramètre contrôle aussi le seuil de report
+(defer threshold) (signal le plus faible pour lequel le matériel considère le
+canal occupé) et le seuil de cession (handover threshold) (niveau de signal pour
+lequel le matériel commence à chercher un nouveau Point d'Accès).
+.br
+.B Exemple :
+.br
+.I "	iwconfig eth0 sens -80"
+.TP
+.B mode
+Positionne le mode de fonctionnement du matériel, qui dépend de la topologie du
+réseau. Le mode peut être
+.I Ad-Hoc
+(réseau composé d'une seule cellule et sans Point d'Accès),
+.I Managed
+(un noeud se connecte à un réseau composé de plusieurs Points d'Accès, avec
+roaming ou errance),
+.I Master
+(le noeud est le maître qui synchronise ou agit comme un Point d'Accès),
+.I Repeater
+(le noeud transmet les paquets entre les autres n½uds wireless),
+.I Secondary
+(le noeud agit comme un maître/répéteur supplémentaire),
+.I Monitor
+(le noeud agit comme un moniteur passif et ne fait que recevoir des paquets) ou
+.IR Auto .
+.br
+.B Exemple :
+.br
+.I "	iwconfig eth0 mode Managed"
+.br
+.I "	iwconfig eth0 mode Ad-Hoc"
+.TP
+.B ap
+Force la carte à s'enregistrer auprès du Point d'Accès donné par l'adresse,
+si c'est possible. Quand la qualité de la connexion devient trop mauvaise,
+le pilote peut revenir en mode automatique (la carte sélectionne le meilleur
+Point d'Accès à portée).
+.br
+Vous pouvez aussi utiliser
+.I off
+pour réactiver le mode automatique sans changer le Point d'Accès courant,
+ou vous pouvez utiliser
+.I any
+ou
+.I auto
+pour forcer la carte à se ré associer avec le meilleur Point d'Accès courant.
+.br
+.B Exemple :
+.br
+.I "	iwconfig eth0 ap 00:60:1D:01:23:45"
+.br
+.I "	iwconfig eth0 ap any"
+.br
+.I "	iwconfig eth0 ap off"
+.TP
+.BR nick [name]
+Positionne le surnom (nickname), ou nom de station. Quelques produits
+802.11 le définissent, mais il n'est pas utilisé dans la mesure où les
+protocoles les plus usités (MAC, IP, TCP) ne s'en servent pas en l'état.
+Seuls quelques outils de diagnostic peuvent l'utiliser.
+.br
+.B Exemple :
+.br
+.I "	iwconfig eth0 nickname ""My Linux Node""
+.TP
+.BR rate / bit [rate]
+Pour les cartes supportant plusieurs débits, positionne le débit en b/s. Le
+débit est la vitesse à laquelle les bits sont transmis sur le médium, la
+vitesse du lien pour l'utilisateur est inférieure à cause du partage du médium
+et des diverses entêtes.
+.br
+Vous pouvez ajouter le suffixe k, M ou G à la valeur (multiplicateur décimal\ :
+10^3, 10^6 et 10^9\ b/s), ou ajouter suffisamment de «\ 0\ ». Les valeurs
+en-dessous de 1000 sont spécifiques à la carte, habituellement un index de la
+liste des débit supportés. Utilisez
+.I auto
+pour sélectionner le mode débit automatique (repli à un débit moindre pour
+les canaux bruités), ce qui est le mode par défaut pour la plupart des cartes,
+et
+.I fixed
+pour revenir à des paramètres fixes. Si vous spécifiez une valeur de débit
+et ajoutez
+.IR auto ,
+le driver utilisera tous les débits inférieurs et égaux à cette valeur.
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 rate 11M"
+.br
+.I "	iwconfig eth0 rate auto"
+.br
+.I "	iwconfig eth0 rate 5.5M auto"
+.TP
+.BR rts [_threshold]
+RTS/CTS ajoute une «\ poignée de main\ » avant chaque transmission de paquet
+pour être sûr que le canal est libre. Cela ajoute des entêtes (NDT\ : données de
+gestion), mais augmente les performances en cas de n½uds cachés ou
+d'un grand nombre de noeuds actifs. Ce paramètre fixe la taille du plus petit
+paquet pour lequel le noeud envoie un RTS\ ; une valeur égale à la taille
+maximale des paquets inhibe ce mécanisme. Vous pouvez aussi positionner
+ce paramètre sur
+.IR auto ", " fixed " ou " off .
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 rts 250"
+.br
+.I "	iwconfig eth0 rts off"
+.TP
+.BR frag [mentation_threshold]
+La fragmentation permet de découper un paquet IP en une série de plus petits
+fragments transmis par le médium. Dans la plupart des cas, cela ajoute des
+entêtes, mais dans un environnement très bruité, cela réduit les coûts de
+transmission dus aux erreurs et permet aux paquets d'être acheminés malgré
+des séries d'interférences. Ce paramètre fixe la taille de fragment maximale\ ;
+une valeur égale à la taille maximale de paquet désactive ce procédé. Vous
+pouvez aussi mettre ce paramètre à
+.IR auto ", " fixed " ou " off .
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 frag 512"
+.br
+.I "	iwconfig eth0 frag off"
+.TP
+.BR key / enc [ryption]
+Utilisé pour manipuler les clefs de cryptage ou brouillage et le mode de
+sécurité.
+.br
+Pour mettre la clef courante de cryptage, il suffit d'entrer la clef
+en hexadécimal telle que
+.IR XXXX-XXXX-XXXX-XXXX " ou " XXXXXXXX .
+Pour entrer une autre clef que la clef courante, ajoutez (au début ou à la
+fin)
+.I [index]
+à la clef elle-même (cela ne changera pas la clef active). Vous pouvez aussi
+entrer la clef comme une chaîne ASCII en utilisant le préfixe
+.IR s: .
+Les phrases en tant que mot de passe ne sont actuellement pas supportées.
+.br
+Pour changer la clef active parmi les clefs déjà entrées, il suffit d'entrer
+.RI l' "[index]"
+(sans entrer de valeur de clef).
+.br
+.IR off " et " on
+désactive et réactive le cryptage.
+.br
+Le mode de sécurité peut être
+.I open
+ou
+.IR restricted ,
+et sa signification dépend de la carte utilisée. Avec la plupart des cartes,
+le mode
+.I open
+n'utilise pas d'authentification et la carte accepte des sessions non cryptées,
+alors que le mode
+.I restricted
+n'accepte que des sessions cryptées et la carte utilisera l'authentification
+si disponible.
+.br
+Si vous avez besoin de mettre plusieurs clefs, ou de mettre une clef et de
+changer la clef active, vous avez besoin d'utiliser des instructions à clefs
+.RB ( "key" )
+multiples. Les arguments peuvent être mis dans n'importe quel ordre, le
+dernier sera prioritaire.
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 key 0123-4567-89"
+.br
+.I "	iwconfig eth0 key [3] 0123-4567-89"
+.br
+.I "	iwconfig eth0 key s:password [2]"
+.br
+.I "	iwconfig eth0 key [2]"
+.br
+.I "	iwconfig eth0 key open"
+.br
+.I "	iwconfig eth0 key off"
+.br
+.I "	iwconfig eth0 key restricted [3] 0123456789"
+.br
+.I "	iwconfig eth0 key 01-23 key 45-67 [4] key [4]"
+.TP
+.BR power
+Utilisé pour manipuler les paramètres et le mode du procédé de gestion
+d'énergie.
+.br
+Pour fixer la période entre les éveils, entrez la
+.IR "period `valeur'" .
+Pour fixer la temporisation avant le retour en veille, entrez la
+.IR "timeout `valeur'" .
+Vous pouvez aussi ajouter les modificateurs
+.IR min " et " max ".
+Par défaut, ces valeurs sont exprimées en secondes, ajoutez le suffixe m ou u
+pour spécifier les valeurs en millisecondes ou microsecondes. Parfois, ces
+valeurs sont sans unité (nombre de périodes de beacon, dwell ou similaire).
+.br
+.IR off " et " on
+désactive et réactive la gestion d'énergie. Enfin, vous pouvez mettre la
+gestion d'énergie en mode
+.I all
+(reçoit tous les paquets),
+.I unicast
+(reçoit seulement les paquets unicast, ignore les paquets multicast et de
+broadcast) et
+.I multicast
+(reçoit seulement les paquets multicast et de broadcast, ignore l'unicast).
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 power period 2"
+.br
+.I "	iwconfig eth0 power 500m unicast"
+.br
+.I "	iwconfig eth0 power timeout 300u all"
+.br
+.I "	iwconfig eth0 power off"
+.br
+.I "	iwconfig eth0 power min period 2 power max period 4"
+.TP
+.BR txpower
+Pour les cartes supportant plusieurs puissances de transmission, règle la
+puissance de transmission en dBm. Si
+.I W
+est la puissance en Watt, la puissance en dBm est
+.IR "P\ =\ 30\ +\ 10.log(W)" .
+Si la valeur est post fixée par
+.IR mW ,
+elle sera automatiquement convertie en dBm.
+.br
+De plus,
+.IR on " et " off
+active et désactive la radio, et
+.IR auto " et " fixed
+active et désactive le contrôle de puissance (si ces fonctions sont
+disponibles).
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 txpower 15"
+.br
+.I "	iwconfig eth0 txpower 30mW"
+.br
+.I "	iwconfig eth0 txpower auto"
+.br
+.I "	iwconfig eth0 txpower off"
+.TP
+.BR retry
+La plupart des cartes supportent les retransmissions MAC (contrôle d'accès
+au médium), et certaines permettent le paramétrage du mécanisme des tentatives
+(en cas d'échec).
+.br
+Pour fixer le nombre maximum d'essais, entrez
+.IR "limit `valeur'" .
+C'est une valeur absolue (sans unité).
+Pour fixer le temps maximum autorisé au mécanisme MAC pour ses tentatives,
+entrez
+.IR "lifetime `valeur'" .
+Par défaut, cette valeur est en secondes, ajouter le suffixe m ou u pour
+spécifier les valeurs en millisecondes ou microsecondes.
+.br
+Vous pouvez aussi ajouter les modificateurs
+.IR min " et " max ".
+Si la carte supporte le mode automatique, ils définissent les limites du
+lifetime, ou les limites inférieure et supérieure (NDT\ : de l'intervalle
+temporel dans lequel le mécanisme MAC est autorisé à réitérer ses tentatives).
+D'autres cartes définissent des valeurs différentes en fonction de la taille
+des paquets, par exemple la norme 802.11 définit une
+.I min limit
+qui est la limite inférieure d'essai (paquets non RTS/CTS).
+.br
+.B Exemples :
+.br
+.I "	iwconfig eth0 retry 16"
+.br
+.I "	iwconfig eth0 retry lifetime 300m"
+.br
+.I "	iwconfig eth0 retry min limit 8"
+.TP
+.BR commit
+Certaines cartes peuvent ne pas appliquer immédiatement les changements
+effectués par les Wireless Extensions (elles peuvent attendre pour prendre en
+compte les changements ou les appliquer seulement quand la carte est montée via
+ifconfig). Cette commande (si disponible) force la carte à appliquer les
+changements en suspens.
+.br
+Cela n'est normalement pas nécessaire, car la carte appliquera éventuellement
+les changements, mais peut être utile pour débuggage.

+.TP
+.BR "Access Point" / Cell
+Une adresse égale à 00:00:00:00:00:00 signifie que la carte n'a pas réussi à

+.B Link quality
+Qualité globale du lien. Peut être basé sur le niveau de contention ou des

+.SH AFFICHAGE
+Il y a deux classes de Wireless Events.
+.PP
+La première classe regroupe les événements relatifs à un changement des
+paramètres du sans fil sur l'interface (typiquement fait par
+.B iwconfig
+ou un script appelant
+.BR iwconfig ).
+Seuls les paramètres qui peuvent entraîner une perturbation de la connectivité
+sont rapportés. Les événements actuellement rapportés changent un des paramètres
+suivants\ :
+.br
+.I "	Network ID"
+.br
+.I "	ESSID"
+.br
+.I "	Frequency"
+.br
+.I "	Mode"
+.br
+.I "	Encryption"
+.br
+Tous ces événements seront générer sur toutes les interfaces sans fil par le
+sous-système «\ wireless\ » du noyau (mais seulement si le pilote a été converti
+àl'API du nouveau pilote).
+.PP
+La deuxième classe d'événements concerne ceux générés par le matériel, lorsque
+quelque chose arrive ou qu'une tâche s'est terminée. Ces événements incluent\ :
+.TP
+.B New Access Point/Cell address
+L'interface a joint un nouveau point d'accès ou cellule ad hoc, ou perdu son
+association avec. Il s'agit de la même adresse MAC affiché par
+.BR iwconfig .
+.TP
+.B Scan request completed
+Une requête de balayage (scanning) a été achevée, les résultats du «\ scan\ »
+sont disponibles (voir
+.BR iwlist ).
+.TP
+.B Tx packet dropped
+Un paquet à destination de cette adresse a été rejeté car l'interface croit que
+ce noeud ne répond plus (habituellement, le seuil maximum des émissions de la
+couche MAC est atteint). C'est habituellement la première indication pouvant
+révéler que le noeud a quitté la cellule ou est hors de portée, mais cela peut
+être due à une atténuation ou une contention excessive.
+.TP
+.B Custom driver event
+Événement spécifique au pilote. Veuillez consulter la documentation du pilote.
+.TP
+.B Registered node

+.B Spy threshold crossed
+La force du signal pour une des adresses de la «\ spy list\ » (NDT\ : voir

+.SH PARAMÈTRES
+.TP
+.BR scan [ning]
+Donne la liste des Points d'Accès et des cellules Ad-Hoc à portée, et
+optionnellement plein d'autres informations à leur propos (ESSID, Quality,
+Frequency, Mode...). Le type d'information retourné dépend de ce que la carte
+supporte.
+.br
+Le «\ Triggering scanning\ » est une opération nécessitant les privilèges
+de
+.I root
+et les utilisateurs normaux peuvent juste lire les résultats («\ letf-over scan
+results\ »). Par défaut, les paramètres courants du pilote auront une grande
+incidence sur la manière dont le scan est réalisé (la boucle du scan). Aussi,
+cette commande est supposée prendre des arguments supplémentaires pour contrôler
+le comportement du scan, mais cela n'est actuellement pas implémenté.
+.TP
+.BR freq [uency]/ channel
+Donne la liste des fréquences disponibles du périphérique et le nombre de canaux
+définis. Veuillez noter que, habituellement, le pilote retourne le nombre total
+de canaux et seulement les fréquences disponibles dans la région considérée,
+donc il n'y a pas correspondance entre le nombre de fréquences affichées et le
+nombre de canaux.
+.TP
+.BR rate / bit [rate]
+Liste les débits supportés par le périphérique (en b/s).
+.TP
+.BR key / enc [ryption]
+Liste les tailles des clefs de cryptage supportées et affiche toutes
+les clefs de cryptage disponibles dans le périphérique.

+et la durée de vie des tentatives («\ retry lifetime\ ») du périphériques
+(NDT\ : voir la section
+.B retry
+de iwconfig(8)).
+.TP
+.BR ap / accesspoint / peers
+Donne la liste des Points d'Accès à portée, et optionnellement la qualié de leur
+lien. Cette option est
+.B obsolète
+et est maintenant dépréciée en faveur du support scan (voir ci-dessus), et la

+.\" DESCRIPTION part
+.\"
+.SH DESCRIPTION
+.B Ifrename 
+is a tool allowing you to assign a consistent name to each of your
+network interface.
+.PP
+By default, interface names are dynamic, and each network interface is
+assigned the first available name
+.RI ( eth0 ", " eth1 "...)."
+The order network interfaces are created may vary. For built-in
+interfaces, the kernel boot time enumeration may vary. For removable
+interface, the user may plug them in any order.
+.PP
+.B Ifrename
+allow the user to decide what name a network interface will have.
+.B Ifrename 
+can use a variety of
+.I selectors
+to specify how interface names match the network interfaces on the
+system, the most common selector is the interface 
+.IR "MAC address" .
+.PP
+.B Ifrename
+must be run before interfaces are brought up, which is why it's mostly
+useful in various scripts (init, hotplug) but is seldom used directly
+by the user. By default,
+.B ifrename 
+renames all present system interfaces using mappings defined in
+.IR /etc/iftab .
+.\"
+.\" PARAMETER part
+.\"
+.SH PARAMETERS
+.TP
+.BI "-c " configfile
+Set the configuration file to be used (by default 
+.IR /etc/iftab ).
+The configuration file define the mapping between selectors and
+interface names, and is described in
+.IR iftab (5).
+.br
+If
+.I configfile
+is "-", the configuration is read from stdin.
+.TP
+.B -p
+Probe (load) kernel modules before renaming interfaces. By default
+.B ifrename 
+only check interfaces already loaded, and doesn't auto-load the
+required kernel modules. This option enables smooth integration with
+system not loading modules before calling
+.BR ifrename .
+.TP
+.B -d
+Enable various
+.B Debian
+specific hacks. Combined with
+.BR -p ,
+only modules for interfaces specified in
+.I /etc/network/interface
+are loaded.
+.TP
+.BI "-i " interface
+Only rename the specified
+.I interface 
+as opposed to all interfaces on the system. The new interface name is
+printed.
+.TP
+.BI "-n " newname
+When used with
+.IR -i ,
+specify the new name of the interface. The list of mappings from the
+configuration file is bypassed. The new name may be a wildcard
+containing a single '*'.
+.TP
+.B -t
+Enable name takeover support. This allow interface name swapping
+between two or more interfaces.
+.br
+Takeover enable an interface to 'steal' the name of another
+interface. This works only with kernel 2.6.X and if the other
+interface is down. Consequently, this is not compatible with
+Hotplug. The other interface is assigned a random name, but may be
+renamed later with 'ifrename'.
+.br
+The number of takeovers is limited to avoid circular loops, and
+therefore some complex multi-way name swapping situations may not be
+fully processed.
+.br
+In any case, name swapping and the use of this feature is discouraged,
+and you are invited to choose unique and unambiguous names for your
+interfaces...
+.TP
+.B -D
+Dry-run mode. Ifrename won't change any interface, it will only print
+new interface name, if applicable, and return.
+.br
+In dry-run mode, interface name wildcards are not resolved. New
+interface name is printed, even if it is the same as the old name.
+.TP
+.B -V
+Verbose mode. Ifrename will display internal results of parsing its
+configuration file and querying the interfaces selectors. Combined
+with the
+.I dry-run
+option, this is a good way to debug complex configurations or trivial
+problems.

+.\"
+.\" DESCRIPTION part
+.\"
+.SH DESCRIPTION
+The file
+.B /etc/iftab
+contains descriptive information about the various network interfaces.
+.B iftab
+is only used by the program
+.IR ifrename (8)
+to assign a consistent network interface name to each network interface.
+.PP
+.B /etc/iftab
+defines a set of
+.IR mappings .
+Each mapping contains an interface name and a set of selectors. The
+selectors allow
+.B ifrename
+to identify each network interface on the system. If a network
+interface matches all descriptors of a mapping,
+.B ifrename
+attempt to change the name of the interface to the interface name
+given by the mapping.
+.\"
+.\" MAPPINGS part
+.\"
+.SH MAPPINGS
+Each mapping is described on a separate line, it starts with an
+.IR "interface name" ,
+and contains a set of
+.IR descriptors ,
+separated by space or tabs.
+.PP
+The relationship between descriptors of a mapping is a
+.IR "logical and" .
+A mapping matches a network interface only is all the descriptors
+match. If a network interface doesn't support a specific descriptor,
+it won't match any mappings using this descriptor.
+.PP
+If you want to use alternate descriptors for an interface name
+(logical or), specify two different mappings with the same interface
+name (one on each line).
+.B Ifrename
+always use the first matching mapping starting from the
+.I end
+of
+.BR iftab ,
+therefore more restrictive mapping should be specified last.
+.\"
+.\" INTERFACE NAME part
+.\"
+.SH INTERFACE NAME
+The first part of each mapping is an interface name. If a network
+interface matches all descriptors of a mapping,
+.B ifrename
+attempt to change the name of the interface to the interface name
+given by the mapping.
+.PP
+The interface name of a mapping is either a plain interface name (such as
+.IR eth2 " or " wlan0 )
+or a interface name pattern containing a single wildcard (such as
+.IR eth* " or " wlan* ).
+In case of wildcard, the kernel replace the '*' with the lowest
+available integer making this interface name unique.
+.\"
+.\" DESCRIPTORS part
+.\"
+.SH DESCRIPTORS
+Each descriptor is composed of a descriptor name and descriptor
+value. Descriptors specify a static attribute of a network interface,
+the goal is to uniquely identify each piece of hardware.
+.PP
+Most users will only use the
+.B mac
+selector, other selectors are for more specialised setup.
+.TP
+.BI mac " mac address"
+Matches the MAC Address of the interface with the specified MAC
+address. The MAC address of the interface can be shown using
+.IR ifconfig (8)
+or
+.IR ip (8).
+The specified MAC address may contain a '*' for wilcard matching.
+.br
+This is the most common selector, as most interfaces have a unique MAC
+address allowing to identify network interfaces without ambiguity.
+However, some interfaces don't have a valid MAC address until they are
+brought up, in such case using this selector is tricky.
+.TP
+.BI arp " arp type"
+Matches the ARP Type (also called Link Type) of the interface with the
+specified ARP type. The ARP Type of the interface can be shown using
+.IR ifconfig (8)
+or
+.IR ip (8).
+.br
+This selector is useful when a driver create multiple network
+interfaces for a single network card.
+.TP
+.BI driver " driver name"
+Matches the Driver Name of the interface with the specified driver
+name. The Driver Name of the interface can be shown using
+.IR "ethtool -i" (8).
+.TP
+.BI businfo " bus information"
+Matches the Bus Information of the interface with the specified bus
+information. The Bus Information of the interface can be shown using
+.IR "ethtool -i" (8).
+.TP
+.BI firmware " firmware revision"
+Matches the Firmware Revision of the interface with the firmware
+revision information. The Firmware Revision of the interface can be
+shown using
+.IR "ethtool -i" (8).
+.TP
+.BI baseaddress " base address"
+Matches the Base Address of the interface with the specified base
+address. The Base Address of the interface can be shown using
+.IR ifconfig (8).
+.br
+Because most cards use dynamic allocation of the Base Address, this
+selector is only useful for ISA and EISA cards.
+.TP
+.BI irq " irq line"
+Matches the IRQ Line (interrupt) of the interface with the specified
+IRQ line. The IRQ Line of the interface can be shown using
+.IR ifconfig (8).
+.br
+Because there are IRQ Lines may be shared, this selector is usually
+not sufficient to uniquely identify an interface.
+.TP
+.BI iwproto " wireless protocol"
+Matches the Wireless Protocol of the interface with the specified
+wireless protocol. The Wireless Protocol of the interface can be shown
+using
+.IR iwconfig (8).
+.br
+This selector is only supported on wireless interfaces and is not
+sufficient to uniquely identify an interface.
+.TP
+.BI pcmciaslot " pcmcia slot"
+Matches the Pcmcia Socket number of the interface with the specified
+slot number. Pcmcia Socket number of the interface can be shown
+using
+.IR "cardctl ident" (8).
+.br
+This selector is usually only supported on 16 bits cards, for 32 bits
+cards it is advised to use the selector
+.BR businfo .

 /*
+ * BASIC PRINCIPLE
+ * ---------------
+ *	Wireless Extension recognise that each wireless device has some
+ * specific features not covered by the standard wireless extensions.
+ * Private wireless ioctls/requests allow a device to export the control
+ * of those device specific features, and allow users to directly interact
+ * with your driver.
+ *	There are many other ways you can implement such functionality :
+ *		o module parameters
+ *		o netlink socket
+ *		o file system (/proc/ or /sysfs/)
+ *		o extra character device (/dev/)
+ *	Private wireless ioctls is one of the simplest implementation,
+ * however it is limited, so you may want to check the alternatives.
+ *
+ *	Like for standard Wireless Extensions, each private wireless
+ * request is identified by an IOCTL NUMBER and carry a certain number
+ * of arguments (SET or GET).
+ *	The driver exports a description of those requests (ioctl number,
+ * request name, set and get arguments). Then, iwpriv uses those request
+ * descriptions to call the appropriate request and handle the
+ * arguments.
+ *

+ *
+ * INLINING vs. POINTER :
+ * --------------------
+ *	One of the tricky aspect of the old driver API is how the data
+ * is handled, which is how the driver is supposed to extract the data
+ * passed to it by iwpriv.
+ *	1) If the data has a fixed size (private ioctl definition
+ * has the flag IW_PRIV_SIZE_FIXED) and the byte size of the data is
+ * lower than 16 bytes, the data will be inlined. The driver can extract
+ * data in the field 'u.name' of the struct iwreq.
+ *	2) If the if the data doesn't have a fixed size or is larger than
+ * 16 bytes, the data is passed by pointer. struct iwreq contains a
+ * struct iwpoint with a user space pointer to the data. Appropriate
+ * copy_from/to_user() function should be used.
+ *	
+ *	With the new API, this is handled transparently, the data is
+ * always available as the fourth argument of the request handler
+ * (usually called 'extra').
  *
  * SET/GET CONVENTION :
  * ------------------
- *	The regular Wireless Extensions use a SET/GET convention, where
- * the low order bit identify a SET (0) or a GET (1) request.
- *	The new ioctl range enforce the SET convention : SET request will

+ *
+ *	The regular Wireless Extensions use the SET/GET convention, where

+ * Wireless Extension is not as restrictive, but still has some
+ * limitations.
+ *	The new ioctl range enforces the SET convention : SET request will
  * be available to root only and can't return any arguments. If you don't
  * like that, just use every other two ioctl.

+ * iwreq_data)). If you don't like that, you can either use the Token Index
+ * support or the old API (aka the ioctl handler).
  *	In any case, it's a good idea to not have ioctl with both SET
  * and GET arguments. If the GET arguments doesn't fit within
  * (union iwreq_data) and SET do, or vice versa, the current code in iwpriv
  * won't work. One exception is if both SET and GET arguments fit within
  * (union iwreq_data), this case should be handled safely in a GET
  * request.

-.B Iwredir
-is used to enable the use multiple version of the Wireless Tools on
-the same system.
-.B Iwredir
-pick the proper version of the wireless tools based on the version of
-Wireless Extension of the current kernel.
-.PP
-A version of the Wireless Tools need to be compiled for each version
-of Wireless Extensions expected to be used (this require specific
-.I make
-instructions), and each tool name need to be suffixed by the WE
-version (ex.
-.I iwconfig16
-for the binary of iwconfig compiled for Wireless Extension 16).
-.br
-Then,
-.B iwredir
-need to be installed under the name of each of the tool that need
-redirection
-.RI "(" iwconfig ", " iwlist "...)."
-.br
-.B Iwredir
-just adds the version of WE from the current kernel to the name it was
-called and executed the resulting command name. If the user invoque
-.I iwlist
-(that is now replaced with
-.IR iwredir )
-and the current kernel has WE version
-.IR 17 ,
-the final command executed will be
-.IR iwlist17 .
-.br
-.B Iwredir
-will read the Wireless Extension version of the current kernel from
-.IR /proc/net/wireless .
-.PP
-.B Iwredir
-works only for Wireless Extension 16 and later, all previous version
-of WE are assumed to be version 15 or version 11.
-.B Iwredir
-is usually not installed by default and is expected to be used only by
-.I advanced
-users.

+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands.  This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ *	# net/core/dev.c (two place + add include)
+ *	# net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ *	# net/core/dev.c (two other places)
+ *	# include/linux/netdevice.h (one place)
+ *	# include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ *	# include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ *	# net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ *	# net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...
