14/************************** DOCUMENTATION **************************/
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...
