QEMU currently aborts when being started with "-nic model=rocker" or with "-net nic,model=rocker". This happens because the "rocker" device is not a normal NIC but a switch, which has different properties. Thus we should only consider real NIC devices for "-nic" and "-net". These devices can be identified by the "netdev" property, so check for this property before adding the device to the list.
