 /************************** 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 :
          *# include/linux/wireless.c
  *
  * Wireless Events (2002 -> onward) :
  * --------------------------------
  * Events are defined at the end of this file, and implemented in :
          *# include/linux/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...
