Subject: mac80211: fix WMM AC default for non-QoS data frames
X-Git-Tag: v2.6.34-rc1~233^2~49^2~240

mac80211: fix WMM AC default for non-QoS data frames

The WMM AC selection added to the monitor mode selection function
accidentally assigns non-QoS data frames to the same AC as mgmt frames
(VO). This is not serious, but should be fixed anyway. This patch
assigns them to the BE AC instead.
