[PATCH 5.17 0603/1126] mt76: mt7915: fix the muru tlv issue

From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 05:11:06 EST


From: MeiChia Chiu <meichia.chiu@xxxxxxxxxxxx>

[ Upstream commit d98a72725bc96c98f68eac12e5a91ec349322c88 ]

The muru enable/disable are only set after the first station connection.
Without this patch, the firmware couldn't enable muru
if the first connected station is non-HE type.
