Subject: [PATCH 1/2] mt76: fix handling ps-poll frames
Date: Sat, 29 Sep 2018 15:05:49 +0200 [thread overview]
Message-ID: <20180929130550.86187-1-nbd@nbd.name> (raw)
Hardware station lookup for pspoll frames can fail, which makes the driver
ignore ps-poll frames. Fix the resulting powersave issues by looking up
the station for pspoll frames in software
