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... 68 */ 69 70 /***************************** INCLUDES *****************************/ 71 72 /* This header is used in user-space, therefore need to be sanitised 73 * for that purpose.
