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... | |
