| 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. |
