From: Felix Fietkau Date: Tue, 13 Nov 2018 20:29:03 +0100 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.
