This patch creates new cfg80211 wiphy API for channel and bitrate
registration and converts mac80211 and drivers to the new API. The
old mac80211 API is completely ripped out.
Along with the regulatory code I've also ripped out the
IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be
unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty
much required for travelling.
Additionally, the patch adds proper "basic" rate handling for STA
mode interface, AP mode interface will have to have new API added
to allow userspace to set the basic rate set, currently it'll be
empty...
Here are a few more TODOs:
* reimplement channel use calculations... they looked too broken to
worry about right now
* convert drivers other than b43

- * This regulatory domain control implementation is known to be incomplete

- *
- * For now, drivers wishing to control which channels are and aren't available

- * - set the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag
- * - continue to include *ALL* possible channels in the modes registered

- * - for each allowable ieee80211_channel structure registered in the above
- * call, set the flag member to some meaningful value such as
- * IEEE80211_CHAN_W_SCAN | IEEE80211_CHAN_W_ACTIVE_SCAN |
- * IEEE80211_CHAN_W_IBSS.
- * - leave flag as 0 for non-allowable channels
- *
- * The usual implementation is for a driver to read a device EEPROM to
- * determine which regulatory domain it should be operating under, then
- * looking up the allowable channels in a driver-local table, then performing

It's simple, sure, but no. Let's not change userspace facing behavior if we
can. If you really need to, use "IEEE 802.11".
Also.. do you really need to rename ieee80211_rate to ieee80211_bitrate? Seems
all the same to me and I would prefer a shorter name.
Thanks,

Sorry. The only thing I really did was a few cleanups, but I found a few
problems with it too, namely a NULL pointer deref when receiving packets
w/o STA (so w/o sdata)

Yeah but it's never ever going to get used. Bet you 10 us pesos on it. So
what's the point? If you feel this makes mac80211 better fit the theory,
well.. whatever..

I'm not even sure what the intention of this ioctl is suppose to be (verify
presence of WE? there are WE implemented ioctls that can be used for that
trick..) but it does indicate it's not for saying what the name of the driver
is and I don't think driver subsystem names count either.
Indicating mode this way is dumb for sure but it fits with the examples given
for the ioctl. Doubt anyone is counting on that though since this ioctl has
been abused already (eg. association status in ipw2200) so "IEEE 802.11"
should be fine.

I disagree. It's literally two lines of code (one defining it and one
using it) and makes things more easy to discover when writing a driver.

changed too

Ok, changed.

It's pretty dumb to indicate the mode that way, but I changed it to just
"IEEE 802.11" now.
Will repost later.
