If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 563e6dd35b0d250f7d586be3317baf278a27ccfa Author: Felix Fietkau <nbd@xxxxxxxx> Date: Thu Nov 25 10:42:12 2021 +0100 mt76: mt7615: improve wmm index allocation [ Upstream commit 70fb028707c8871ef9e56b3ffa3d895e14956cc4 ] Typically all AP interfaces on a PHY will share the same WMM settings, while sta/mesh interfaces will usually inherit the settings from a remote device. In order minimize the likelihood of conflicting WMM settings, make all AP interfaces share one slot, and all non-AP interfaces another one. This also fixes running multiple AP interfaces on MT7613, which only has 3 WMM slots.
