Wouldn't it make sense to add eth1 port to the > integration mode. you might have quantum networks that use vlans on different on different physical NICs (e.g., eth0 and eth1), so adding each NIC directly to br-int wouldn't make sense. Similarly, you might have some quantum networks that also use tunneling. Hence, all vNICs are just plugged into br-int, and the plugin is responsible for doing the right thing with the traffic.
