From: wenxu <wenxu@chinatelecom.cn>

Add vlan_filtering enabled bridge and vlan case.
Add a vlan_filtering bridge device to the Router1 (nsr1) container
and attach the veth0 device to the bridge. Set the IP address to
the bridge device to exercise the bridge forwarding path.
The veth0 add in the vlan 10 domain and the br0 also add in the
vlan 10 domain with untaged.
