Bug Description
If you reload/restart the neutron-openvswitch daemon it will first throw away all existing flows.
This will break all networking until the flows are re-created.
It can take some time before everything is back in the flow table on machines with quite a bit of instances or a busy neutron server.
Please make the clearing of the flows optional during a restart.
