| 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 | * # 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 |
| 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... |
