13/************************** DOCUMENTATION **************************/
14/*
15 * Initial APIs (1996 -> onward) :
16 * -----------------------------
17 * Basically, the wireless extensions are for now a set of standard ioctl
18 * call + /proc/net/wireless
19 *
20 * The entry /proc/net/wireless give statistics and information on the
21 * driver.
22 * This is better than having each driver having its entry because
23 * its centralised and we may remove the driver module safely.
24 *
25 * Ioctl are used to configure the driver and issue commands. This is
26 * better than command line options of insmod because we may want to
27 * change dynamically (while the driver is running) some parameters.
28 *
29 * The ioctl mechanimsm are copied from standard devices ioctl.
30 * We have the list of command plus a structure descibing the
31 * data exchanged...
32 * Note that to add these ioctl, I was obliged to modify :
33 * # net/core/dev.c (two place + add include)
34 * # net/ipv4/af_inet.c (one place + add include)
35 *
36 * /proc/net/wireless is a copy of /proc/net/dev.
37 * We have a structure for data passed from the driver to /proc/net/wireless
38 * Too add this, I've modified :
39 * # net/core/dev.c (two other places)
40 * # include/linux/netdevice.h (one place)
41 * # include/linux/proc_fs.h (one place)
42 *
43 * New driver API (2002 -> onward) :
44 * -------------------------------
45 * This file is only concerned with the user space API and common definitions.
46 * The new driver API is defined and documented in :
47 * # include/net/iw_handler.h
48 *
49 * Note as well that /proc/net/wireless implementation has now moved in :
50 * # net/core/wireless.c
51 *
52 * Wireless Events (2002 -> onward) :
53 * --------------------------------
54 * Events are defined at the end of this file, and implemented in :
55 * # net/core/wireless.c
56 *
57 * Other comments :
58 * --------------
59 * Do not add here things that are redundant with other mechanisms
60 * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
61 * wireless specific.
62 *
63 * These wireless extensions are not magic : each driver has to provide
64 * support for them...
65 *
66 * IMPORTANT NOTE : As everything in the kernel, this is very much a
67 * work in progress. Contact me if you have ideas of improvements...
