IP_MULTICAST_LOOP should be set to false/0

If IP_MULTICAST_LOOP is left to true/1 the dawn instance will send the packet out and then receive it itself, this will generate a 'Remote PROBE updated client / BSSID = XX:XX:XX:XX:XX:XX / YY:YY:YY:YY:YY:YY' after every 'Local PROBE used to update client / BSSID = XX:XX:XX:XX:XX:XX / YY:YY:YY:YY:YY:YY'
