6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Chiu <chui-hao.chiu@xxxxxxxxxxxx>
[ Upstream commit 376200f095d0c3a7096199b336204698d7086279 ]
During scanning, UNI_CHANNEL_RX_PATH tag is necessary for the firmware to
properly stop and resume MAC TX queue. Without this tag, HW needs more time
to resume traffic when switching back to working channel.
