we now start to maintain our own copy of wireless.h.
this has several advantages, one of the major ones is that we no longer have to compile different libopienet2 for different kernel (read wireless extension) versions.

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 *# include/linux/wireless.c
51 *
52 * Wireless Events (2002 -> onward) :
53 * --------------------------------
54 * Events are defined at the end of this file, and implemented in :
55 *# include/linux/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...
