netvirt 3 node l2 suite randomly fails on VMs failing to get IP :

https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/builder-copy-sandbox-logs/183/faseelanetvirt-csit-3node-openstack-queens-upstream-stateful-fluorine/39/

The IPs are not getting assigned only for network-type-vlan.

And while troubleshooting, it was seen that table 0 entry in the openstack controller node is not proper.

The flow entry corresponding to interface 150501453275533:br-physnet1-pa:1121 is missing.

Also, the corresponding interface is not present in the operational interface DS.
