  15/*
  16 * Initial APIs (1996 -> onward) :
  17 * -----------------------------
  18 * Basically, the wireless extensions are for now a set of standard ioctl
  19 * call + /proc/net/wireless
  20 *
  21 * The entry /proc/net/wireless give statistics and information on the
  22 * driver.
  23 * This is better than having each driver having its entry because
  24 * its centralised and we may remove the driver module safely.
  25 *
  26 * Ioctl are used to configure the driver and issue commands.  This is
  27 * better than command line options of insmod because we may want to
  28 * change dynamically (while the driver is running) some parameters.
  29 *
  30 * The ioctl mechanimsm are copied from standard devices ioctl.
  31 * We have the list of command plus a structure descibing the
  32 * data exchanged...
  33 * Note that to add these ioctl, I was obliged to modify :
  34 *	# net/core/dev.c (two place + add include)
  35 *	# net/ipv4/af_inet.c (one place + add include)
  36 *
  37 * /proc/net/wireless is a copy of /proc/net/dev.
  38 * We have a structure for data passed from the driver to /proc/net/wireless
  39 * Too add this, I've modified :
  40 *	# net/core/dev.c (two other places)
  41 *	# include/linux/netdevice.h (one place)
  42 *	# include/linux/proc_fs.h (one place)
  43 *
  44 * New driver API (2002 -> onward) :
  45 * -------------------------------
  46 * This file is only concerned with the user space API and common definitions.
  47 * The new driver API is defined and documented in :
  48 *	# include/net/iw_handler.h
  49 *
  50 * Note as well that /proc/net/wireless implementation has now moved in :
  51 *	# net/core/wireless.c
  52 *
  53 * Wireless Events (2002 -> onward) :
  54 * --------------------------------
  55 * Events are defined at the end of this file, and implemented in :
  56 *	# net/core/wireless.c
  57 *
  58 * Other comments :
  59 * --------------
  60 * Do not add here things that are redundant with other mechanisms
  61 * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
  62 * wireless specific.
  63 *
  64 * These wireless extensions are not magic : each driver has to provide
  65 * support for them...
  66 *
  67 * IMPORTANT NOTE : As everything in the kernel, this is very much a
  68 * work in progress. Contact me if you have ideas of improvements...
