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.
