From 85a8abf803853a603c342cde92fd528a68c48134 Mon Sep 17 00:00:00 2001 From: Markus Theil Date: Wed, 18 Dec 2019 17:07:49 +0100 Subject: [PATCH] mt76: mt76x02: omit beacon slot clearing mt76 hw does not send beacons from beacon slots, if the corresponding bitmask is set accordingly. Therefore we can omit clearing the beacon memory. Clearing uses many usb calls, if usb drivers are used. These calls unnecessarily slow down the beacon tasklet. Thanks to Stanislaw Gruzska for pointing this out.
