+Subject: [PATCH] mac80211: enable QoS support for nl80211 ctrl port
+
+This patch unifies sending control port frames
+over nl80211 and AF_PACKET sockets a little more.
+
+Before this patch, EAPOL frames got QoS prioritization
+only when using AF_PACKET sockets.
+
+__ieee80211_select_queue only selects a QoS-enabled queue
+for control port frames, when the control port protocol
+is set correctly on the skb. For the AF_PACKET path this
+works, but the nl80211 path used ETH_P_802_3.
+
+Another check for injected frames in wme.c then prevented
+the QoS TID to be copied in the frame.
+
+In order to fix this, get rid of the frame injection marking
+for nl80211 ctrl port and set the correct ethernet protocol.
+
+Please note:
+An erlier version of this path tried to prevent
+frame aggregation for control port frames in order to speed up
+the initial connection setup a little. This seemed to cause
+issues on my older Intel dvm-based hardware, and was therefore
+removed again. Future commits which try to reintroduce this
+have to check carefully how hw behaves with aggregated and
+non-aggregated traffic for the same TID.
