+/*
+ * 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...
