/************************** DOCUMENTATION **************************/
/*
 * 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...
