00021 /* ************************ DOCUMENTATION **************************/
00022 /*
00023  * Initial APIs (1996 -> onward) :
00024  * -----------------------------
00025  * Basically, the wireless extensions are for now a set of standard ioctl
00026  * call + /proc/net/wireless
00027  *
00028  * The entry /proc/net/wireless give statistics and information on the
00029  * driver.
00030  * This is better than having each driver having its entry because
00031  * its centralised and we may remove the driver module safely.
00032  *
00033  * Ioctl are used to configure the driver and issue commands.  This is
00034  * better than command line options of insmod because we may want to
00035  * change dynamically (while the driver is running) some parameters.
00036  *
00037  * The ioctl mechanimsm are copied from standard devices ioctl.
00038  * We have the list of command plus a structure descibing the
00039  * data exchanged...
00040  * Note that to add these ioctl, I was obliged to modify :
00041  *      # net/core/dev.c (two place + add include)
00042  *      # net/ipv4/af_inet.c (one place + add include)
00043  *
00044  * /proc/net/wireless is a copy of /proc/net/dev.
00045  * We have a structure for data passed from the driver to /proc/net/wireless
00046  * Too add this, I've modified :
00047  *      # net/core/dev.c (two other places)
00048  *      # include/linux/netdevice.h (one place)
00049  *      # include/linux/proc_fs.h (one place)
00050  *
00051  * New driver API (2002 -> onward) :
00052  * -------------------------------
00053  * This file is only concerned with the user space API and common definitions.
00054  * The new driver API is defined and documented in :
00055  *      # include/net/iw_handler.h
00056  *
00057  * Note as well that /proc/net/wireless implementation has now moved in :
00058  *      # net/core/wireless.c
00059  *
00060  * Wireless Events (2002 -> onward) :
00061  * --------------------------------
00062  * Events are defined at the end of this file, and implemented in :
00063  *      # net/core/wireless.c
00064  *
00065  * Other comments :
00066  * --------------
00067  * Do not add here things that are redundant with other mechanisms
00068  * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
00069  * wireless specific.
00070  *
00071  * These wireless extensions are not magic : each driver has to provide
00072  * support for them...
00073  *
00074  * IMPORTANT NOTE : As everything in the kernel, this is very much a
00075  * work in progress. Contact me if you have ideas of improvements...
