Subject: [PATCH] mt76: mt7915: fix the muru tlv issue
Date:   Tue, 15 Feb 2022 16:48:58 +0800

From: MeiChia Chiu <meichia.chiu@mediatek.com>

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.
