Is this still being worked on by someone? Seems the merge request is stalled...
If not worked on should the bug be set back to new/confirmed again?
As mentioned this bug is crippling for doing updates on the agent due to the creation of network outages.
Would be very sad to see not have it fixed in this release cycle.

Title:
Restarting neutron openvswitch agent causes network hiccup by throwing
away all flows
Status in OpenStack Neutron (virtual network service):
In Progress
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.
