+Subject: [PATCH] wifi: mt76: ACS channel time too long on duty channel
+
+Step and issue:
+1. Set channel to 36 in hostapd config;
+2. Bootup;
+3. Enable ACS through UCI command and reload;
+4. Check hostapd log, channel 36 channel_time is much longer than other channels.
+
+Root cause:
+The reset chan_stat condition missed duty channel.
+
+Solution:
+When scan start, need to reset chan_stat in each channel switch.
