/************************** DOCUMENTATION **************************/ |
|
/* |
|
* Initial APIs (1996 -> onward) : |
|
* ----------------------------- |
|
* Basically, the wireless extensions are for now a set of standard ioctl |
|
* call + /proc/net/wireless |
|
* |
|
* The entry /proc/net/wireless give statistics and information on the |
|
* driver. |
|
* This is better than having each driver having its entry because |
|
* its centralised and we may remove the driver module safely. |
|
* |
|
* Ioctl are used to configure the driver and issue commands. 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... |
