Received packet with own address as source

[kroese]

When running the container, the log of my host OS gets spammed with this error:

kernel: qemubr0: received packet on eth0 with own address as source address (addr:03:42:ab:11:00:02, vlan:0)

From my research this indicates that there is a loop in the LAN somewhere. So this is probably caused by the bridge interface that gets created when starting the container.

Any clues on how to prevent this error from popping up?
