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