Subject: [PATCH 6/6] wifi: mt76: mt7915: set correct antenna for radar detection on MT7915D
Date: Fri, 30 Sep 2022 23:13:15 +0800	[thread overview]
Message-ID: <20220930151315.19012-6-shayne.chen@mediatek.com> (raw)
In-Reply-To: <20220930151315.19012-1-shayne.chen@mediatek.com>

For MT7915D, correct antenna index should be set to let DFS radar
detection work on the 5 GHz band.
