20/*
21 * Initial APIs (1996 -> onward) :
22 * -----------------------------
23 * Basically, the wireless extensions are for now a set of standard ioctl
24 * call + /proc/net/wireless
25 *
26 * The entry /proc/net/wireless give statistics and information on the
27 * driver.
28 * This is better than having each driver having its entry because
29 * its centralised and we may remove the driver module safely.
30 *
31 * Ioctl are used to configure the driver and issue commands. This is
32 * better than command line options of insmod because we may want to
33 * change dynamically (while the driver is running) some parameters.
34 *
35 * The ioctl mechanimsm are copied from standard devices ioctl.
36 * We have the list of command plus a structure descibing the
37 * data exchanged...
38 * Note that to add these ioctl, I was obliged to modify :
39 * # net/core/dev.c (two place + add include)
40 * # net/ipv4/af_inet.c (one place + add include)
41 *
42 * /proc/net/wireless is a copy of /proc/net/dev.
43 * We have a structure for data passed from the driver to /proc/net/wireless
44 * Too add this, I've modified :
45 * # net/core/dev.c (two other places)
46 * # include/linux/netdevice.h (one place)
47 * # include/linux/proc_fs.h (one place)
48 *
49 * New driver API (2002 -> onward) :
50 * -------------------------------
51 * This file is only concerned with the user space API and common definitions.
52 * The new driver API is defined and documented in :
53 * # include/net/iw_handler.h
54 *
55 * Note as well that /proc/net/wireless implementation has now moved in :
56 * # net/core/wireless.c
57 *
58 * Wireless Events (2002 -> onward) :
59 * --------------------------------
60 * Events are defined at the end of this file, and implemented in :
61 * # net/core/wireless.c
62 *
63 * Other comments :
64 * --------------
65 * Do not add here things that are redundant with other mechanisms
66 * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
67 * wireless specific.
68 *
69 * These wireless extensions are not magic : each driver has to provide
70 * support for them...
71 *
72 * IMPORTANT NOTE : As everything in the kernel, this is very much a
73 * work in progress. Contact me if you have ideas of improvements...
