| Subject: [PATCH 7/7] 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. |
