+
+When using WEP, the default unicast key needs to be selected, instead of

+Subject: [PATCH] mac80211: add rx decapsulation offload support
+
+This allows drivers to pass 802.3 frames to mac80211, with some restrictions:
+
+- the skb must be passed with a valid sta
+- fast-rx needs to be active for the sta
+- monitor mode needs to be disabled
+
+mac80211 will tell the driver when it is safe to enable rx decap offload for
+a particular station.
+
+In order to implement support, a driver must:
+
+- call ieee80211_hw_set(hw, SUPPORTS_RX_DECAP_OFFLOAD)
+- implement ops->sta_set_decap_offload
+- mark 802.3 frames with RX_FLAG_8023
+
+If it doesn't want to enable offload for some vif types, it can mask out
+IEEE80211_OFFLOAD_DECAP_ENABLED in vif->offload_flags from within the
+.add_interface or .update_vif_offload driver ops
