Subject: [PATCH v3 1/4] mt76: fix mt76_rates for the multiple devices
Date:   Wed, 14 Jul 2021 04:15:58 +0800
Message-ID: <92a8ecfdf198b34f98d5c1489a83adf151657760.1626207204.git.objelf@gmail.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

From: Sean Wang <sean.wang@mediatek.com>

PHY offset in either .hw_value or .hw_value_short for mt7615, mt7663,
mt7915 and mt7921 device all start at bit 6, not 8.

Suggested-by: Ryder Lee <ryder.lee@mediatek.com>
Signed-off-by: Sean Wang <sean.wang@mediatek.com>
---
v2: splitted out from the patch ("mt76: mt7921: fix mgmt frame using unexpected bitrate")
    to cover more devices which have the same issue.
v3: no change.
