The Linux Wireless Extensions V16 introduce some massive changes in the
binary structures. Since we still use V15 on most target platforms I have
to introduce two headers. Define OPIE_WE_VERSION to specify which header to include
Diffstat (limited to 'libopie2/opienet/wireless.16.h') (more/less context) (show whitespace changes)

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... | ||
