This is 00026 * better than command line options of insmod because we may want to 00027 * change dynamically (while the driver is running) some parameters. 00028 * 00029 * The ioctl mechanimsm are copied from standard devices ioctl. 00030 * We have the list of command plus a structure descibing the 00031 * data exchanged... 00032 * Note that to add these ioctl, I was obliged to modify : 00033 * # net/core/dev.c (two place + add include) 00034 * # net/ipv4/af_inet.c (one place + add include) 00035 * 00036 * /proc/net/wireless is a copy of /proc/net/dev. 00037 * We have a structure for data passed from the driver to /proc/net/wireless 00038 * Too add this, I've modified : 00039 * # net/core/dev.c (two other places) 00040 * # include/linux/netdevice.h (one place) 00041 * # include/linux/proc_fs.h (one place) 00042 * 00043 * New driver API (2002 -> onward) : 00044 * ------------------------------- 00045 * This file is only concerned with the user space API and common definitions. 00046 * The new driver API is defined and documented in : 00047 * # include/net/iw_handler.h 00048 * 00049 * Note as well that /proc/net/wireless implementation has now moved in : 00050 * # net/core/wireless.c 00051 * 00052 * Wireless Events (2002 -> onward) : 00053 * -------------------------------- 00054 * Events are defined at the end of this file, and implemented in : 00055 * # net/core/wireless.c 00056 * 00057 * Other comments : 00058 * -------------- 00059 * Do not add here things that are redundant with other mechanisms 00060 * (drivers init, ifconfig, /proc/net/dev, ...) and with are not 00061 * wireless specific. 00062 * 00063 * These wireless extensions are not magic : each driver has to provide 00064 * support for them... 00065 * 00066 * IMPORTANT NOTE : As everything in the kernel, this is very much a 00067 * work in progress.
