15
* Initial APIs (1996 -> onward) :
16
* -----------------------------
17
* Basically, the wireless extensions are for now a set of standard ioctl
18
* call + /proc/net/wireless
20
* The entry /proc/net/wireless give statistics and information on the
22
* This is better than having each driver having its entry because
23
* its centralised and we may remove the driver module safely.
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.
29
* The ioctl mechanimsm are copied from standard devices ioctl.
30
* We have the list of command plus a structure descibing the
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)
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)
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
49
* Note as well that /proc/net/wireless implementation has now moved in :
50
* # net/core/wireless.c
52
* Wireless Events (2002 -> onward) :
53
* --------------------------------
54
* Events are defined at the end of this file, and implemented in :
55
* # net/core/wireless.c
59
* Do not add here things that are redundant with other mechanisms
60
* (drivers init, ifconfig, /proc/net/dev, ...) and with are not
63
* These wireless extensions are not magic : each driver has to provide
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...

83
* This constant is used to know the availability of the wireless
84

85

86
* I just plan to increment with each new version.
