From 65d91a833b010c0923866ed362f79898d474451f Mon Sep 17 00:00:00 2001 From: StanleyYP Wang Date: Thu, 31 Aug 2023 14:22:17 +0800 Subject: [PATCH] wifi: mt76: get rid of false alamrs of tx emission issues When the set_chan_info command is set with CH_SWITCH_NORMAL reason, even if the action is UNI_CHANNEL_RX_PATH, it'll still generate some unexpected tones, which might confuse DFS CAC tests that there are some tone leakages. To get rid of these kinds of false alarms, always bypass DPD calibration when IEEE80211_CONF_IDLE is set.
