Plzzz someone explain how WMM is implemented in mac80211 and suggest
some tests so we can be sure we implement it correctly, we really want
to add multiqueue support in ath5k ;-)

Well nobody knows ;)

Also it would be great if someone explained what's new in
802.11n/802.11s and what drivers are expected to do (i think on the
previous summit there was a talk about encrypted management frames, do
we have a plan for that ?).

There's no 11s support yet, the cozybit guys never came forward with a
second patchset after we commented on their first. 11w (encrypted
management frames) is pretty straight forward, we add the new
"encryption" algorithm and wpa_supplicant does the rest (in fact, it
already has code)
