Subject: [PATCH 11/13] wifi: mt76: mt7996: add support for EHT rate report
Date: Tue, 10 Jan 2023 00:57:29 +0800 [thread overview]
Message-ID: <20230109165731.682-12-shayne.chen@mediatek.com> (raw)
In-Reply-To: <20230109165731.682-1-shayne.chen@mediatek.com>
Currenly only EHT TX rate report is supported. EHT RX rate is temporally
reported with HE rate.
