| 4 | Subject: [PATCH 04/15] wifi: mt76: mt7915: get rid of false alamrs of tx |
| 5 | emission issues |
| 6 | |
| 7 | When mt7915_mcu_set_chan_info() is set with CH_SWITCH_NORMAL reason, |
| 8 | even if the action is UNI_CHANNEL_RX_PATH, it'll still generate some |
| 9 | unexpected tones, which might confuse DFS CAC tests that there are some |
| 10 | tone leakages. To get rid of these kinds of false alarms, always bypass |
| 11 | DPD calibration when IEEE80211_CONF_IDLE is set. |
