-[PATCH] mac80211: hoist sta->lock from reorder release timer
-
-The patch "mac80211: AMPDU rx reorder timeout timer" clashes
-with "mac80211: use netif_receive_skb in ieee80211_rx callpath"
-
-The timer itself is part of the station's private struct and
-it gets killed whenever the station is removed. Therefore
-the extra sta->lock protection (that can interferes with the
-tx path) is not necessary.
