Title:
[RFE] Extend l2-extensions-api for flow management
Status in neutron:
Won't Fix
Bug description:
The l2-extensions-api that merged in Mitaka allows extensions of the OvSNeutronAgent to use the OvS flow table.
This introduces a new challenge of interoperability between extensions creating flows.
As the OvS flow table matches traffic to flows based on packet characteristics in the order of priority assigned to the flow,
it will inevitably result in two extensions using flows that will block the extension that uses the lower priority flows.
Therefore a flow manager or flow pipeline is necessary that will prevent extensions from blocking other flows from matching traffic.
