With vlan tenant we have mac-mapping configured in ovs db
for compute nodes. These MAC values should be used when
filtering relevant traffic for east_west communication.
Also, introduced separate tunnel_interface config parameter
to define an appropriate value when capturing traffic on
a normal node and on ovs_pod.
