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... *//***************************** INCLUDES *****************************/#include <linux/types.h> /* for "caddr_t" et al */#include <linux/socket.h> /* for "struct sockaddr" et al */#include <linux/if.h> /* for IFNAMSIZ and co... *//***************************** VERSION *****************************//* * This constant is used to know the availability of the wireless * extensions and to know which version of wireless extensions it is * (there is some stuff that will be added in the future...) * I just plan to increment with each new version. */#define WIRELESS_EXT 19/* * Changes : * * V2 to V3 * -------- * Alan Cox start some incompatibles changes.
