/*

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

*

* Other comments :

* --------------

* 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...
