Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/************************** 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...
