old mac80211 API is completely ripped out. All drivers (except ath5k)

Along with the regulatory code I've also ripped out the

unnecessary if the hardware simply gives us whatever channels it wants
to support and we then enable/disable them as required, which is pretty

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

simultaneously, this is a hardware limitation so future support
will be very unlikely.
Each interface structure receives its dedicated beacon entry,
with this we can easily work with beaconing while multiple master
mode interfaces are currently active.
The configuration handlers for the MAC, BSSID and type are
often called together since they all belong to the interface

Access to the queues is now protected under a spinlock, this

system of the queue.
Each queue entry allocates x bytes for driver/device specific data,
this cleans up the queue structure significantly and improves
code readability.
rt2500usb no longer needs 2 entries in the beacon queue to correctly
send out the guardian byte. This is now handled in the entry specific
structure.
