- 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")
