This is 33 * better than command line options of insmod because we may want to 34 * change dynamically (while the driver is running) some parameters. 35 * 36 * The ioctl mechanimsm are copied from standard devices ioctl. 37 * We have the list of command plus a structure descibing the 38 * data exchanged... 39 * Note that to add these ioctl, I was obliged to modify : 40 * # net/core/dev.c (two place + add include) 41 * # net/ipv4/af_inet.c (one place + add include) 42 * 43 * /proc/net/wireless is a copy of /proc/net/dev. 44 * We have a structure for data passed from the driver to /proc/net/wireless 45 * Too add this, I've modified : 46 * # net/core/dev.c (two other places) 47 * # include/linux/netdevice.h (one place) 48 * # include/linux/proc_fs.h (one place) 49 * 50 * New driver API (2002 -> onward) : 51 * ------------------------------- 52 * This file is only concerned with the user space API and common definitions. 53 * The new driver API is defined and documented in : 54 * # include/net/iw_handler.h 55 * 56 * Note as well that /proc/net/wireless implementation has now moved in : 57 * # net/core/wireless.c 58 * 59 * Wireless Events (2002 -> onward) : 60 * -------------------------------- 61 * Events are defined at the end of this file, and implemented in : 62 * # net/core/wireless.c 63 * 64 * Other comments : 65 * -------------- 66 * Do not add here things that are redundant with other mechanisms 67 * (drivers init, ifconfig, /proc/net/dev, ...) and with are not 68 * wireless specific. 69 * 70 * These wireless extensions are not magic : each driver has to provide 71 * support for them... 72 * 73 * IMPORTANT NOTE : As everything in the kernel, this is very much a 74 * work in progress.
