Merge tag 'mac80211-for-davem-2015-03-16' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
Here are a few fixes that I'd like to still get in:
* disable U-APSD for better interoperability, from Michal Kazior
* drop unencrypted frames in mesh forwarding, from Bob Copeland
* treat non-QoS/WMM HT stations as non-HT, to fix confusion when
they connect and then get QoS packets anyway due to HT
* fix counting interfaces for combination checks, otherwise the
interface combinations aren't properly enforced (from Andrei)
* fix pure ECSA by reacting to the IE change
* ignore erroneous (E)CSA to the current channel which sometimes
happens due to AP/GO bugs
====================
