+Subject: [PATCH 8/8] mt76: mt7915: set the first antenna to detect radar for
+ MT7915
+
+The default value of listening antenna set by FW might be different in
+MT7915. As most of our cooperated labs use the first antenna to verify
+the radar detection function, manually set the value by a mcu command.
