+Subject: [PATCH] mac80211: ignore tx status for PS stations in
+ ieee80211_tx_status_ext
+
+Make it behave like regular ieee80211_tx_status calls, except for the lack of
+filtered frame processing.
+This fixes spurious low-ack triggered disconnections with powersave clients
+connected to an AP.
+
+Fixes: f027c2aca0cf4 ("mac80211: add ieee80211_tx_status_noskb")
