[PATCH 02/12] wifi: mt76: mt7996: fix traffic delay when switching back to working channel

[Shayne Chen]

From: Peter Chiu <chui-hao.chiu at mediatek.com>

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.
