Subject: [PATCH] mac80211: ignore tx status for PS stations in ieee80211_tx_status_ext
Date: Tue, 13 Nov 2018 20:32:13 +0100 [thread overview]
Message-ID: <20181113193213.87628-1-nbd@nbd.name> (raw)
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")
