[Bug 1460164] Re: restart of openvswitch-switch causes instance network down when l2population enabled

[James Page]

The fdb_add method checks to see if the agent already has a registered
ofport for each tunnel it requires - this is now stale, so results in
the tunnel setup being skipped - the tunnel ports are still present in
the ovsdb - however all of the flows are missing resulting in full loss
of instance connectivity.
