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
