Subject: [PATCH 2/2] mt76: mt7915: fix bit fields for HT rate idx
Date: Tue, 20 Jul 2021 21:00:14 +0800 [thread overview]
Message-ID: <20210720130014.23572-2-shayne.chen@mediatek.com> (raw)
In-Reply-To: <20210720130014.23572-1-shayne.chen@mediatek.com>
The bit fields of tx rate idx should be 6 bits, otherwise it might be
incorrect in HT mode.
For VHT/HE rates, only 4 bits are actually used by rate idx, the other
2 bits are used for other functions.
Fixes: c31d94af1843 ("mt76: mt7915: fix tx rate related fields in tx descriptor")
