I did recently rebase that patch to the current mac80211-next, actually.
Sent it off to Felix for some testing, but if you wan to give it a go I
can post it to the list as well :)

I don't think there have been any other patches being actively worked
on, but I seem to recall something about AQL (partly?) breaking airtime
fairness because the scheduler only keeps fairness between stations that
are actually scheduled, and AQL interrupting that...
