| /* |
| * Initial APIs (1996 -> onward) : |
| * ----------------------------- |
| * Basically, the wireless extensions are for now a set of standard ioctl |
| * call + /proc/net/wireless |
| * |
| * The entry /proc/net/wireless give statistics and information on the |
| * driver. |
| * This is better than having each driver having its entry because |
| * its centralised and we may remove the driver module safely. |
| * |
| * Ioctl are used to configure the driver and issue commands. This is |
| * better than command line options of insmod because we may want to |
| * change dynamically (while the driver is running) some parameters. |
| * |
| * The ioctl mechanimsm are copied from standard devices ioctl. |
| * We have the list of command plus a structure descibing the |
| * data exchanged... |
| * Note that to add these ioctl, I was obliged to modify : |
| * # net/core/dev.c (two place + add include) |
| * # net/ipv4/af_inet.c (one place + add include) |
| * |
| * /proc/net/wireless is a copy of /proc/net/dev. |
| * We have a structure for data passed from the driver to /proc/net/wireless |
| * Too add this, I've modified : |
| * # net/core/dev.c (two other places) |
| * # include/linux/netdevice.h (one place) |
| * # include/linux/proc_fs.h (one place) |
| * |
| * New driver API (2002 -> onward) : |
| * ------------------------------- |
| * This file is only concerned with the user space API and common definitions. |
| * The new driver API is defined and documented in : |
| * # include/net/iw_handler.h |
| * |
| * Note as well that /proc/net/wireless implementation has now moved in : |
| * # net/core/wireless.c |
| * |
| * Wireless Events (2002 -> onward) : |
| * -------------------------------- |
| * Events are defined at the end of this file, and implemented in : |
| * # net/core/wireless.c |
| * |
| * Other comments : |
| * -------------- |
| * Do not add here things that are redundant with other mechanisms |
| * (drivers init, ifconfig, /proc/net/dev, ...) and with are not |
| * wireless specific. |
| * |
| * These wireless extensions are not magic : each driver has to provide |
| * support for them... |
| * |
| * IMPORTANT NOTE : As everything in the kernel, this is very much a |
| * work in progress. Contact me if you have ideas of improvements... |
