Looking up the MAC address in the name of that last interface the name says it's from Realtek Semiconductor Corp so it seems unrelated to the other Intel devices. Try looking at the output of 'dmesg' and look for 'Realtek' in the kernal log for a clue. Do you have any other network devices plugged in, perhaps in USB port? Possibly a wifi dongle. Also, a long shot, something could be automagically configuring something like a phone or bluetooth device for network use. -- Tixy
