Subject: [PATCH 3/3] mt76: mt7615: in debugfs queue stats, skip wmm index 3 on mt7663
Date: Wed, 15 Dec 2021 18:38:39 +0100 [thread overview]
Message-ID: <20211215173839.20853-3-nbd@nbd.name> (raw)
In-Reply-To: <20211215173839.20853-1-nbd@nbd.name>
The hardware only supports WMM index 0-2 and registers for index 3 return
bogus data.
