/************************** 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...
