Thanks a lot for investigating this issue so well, looking at the patch
and subsequent fix-ups in hostapd-1.git, I fear it wouldn't be a good 
idea to cherry-pick with to the dormant 0.7.x branch, given that the 
patch as-is breaks QoS and would need rather large fixes down the line.
I will check this a bit more thouroughly, but tend to err on the side 
of caution for the 0.7 branch at the moment.

At this moment, it has not been decided yet, if wheezy will ship 
hostapd/ wpasupplicant 0.7.x or 1.0, as moving to the 1.x branch would 
usually require a 1.0.0 upstream release well in advance to wheezy's 
intended freeze date…
