    Fix DVR to service LBaaS VIP Ports

    Currently, DVR router namespaces are created only
    when there is a valid VM port on the compute
    node, or for the gateway-port on the service node.
    But when an LBaaS VIP port is created the l3 agent
    does not create a DVR namespace to service the VIP port.
    This fix enables DVR namespaces to be created to
    service the LBaaS VIP port.

    Also, this fix enables L2 Agent running in DVR
    mode, to add-in OVS rules to enable packets to
    be routed to such LBaaS VIP Ports which are
    resident on DVR routed interfaces.

    Therefore, with this fix both East-West and
    North-South traffic will be serviced by DVR
    for LBaas VIP Ports.

[Armando Migliaccio (armando-migliaccio)]

I am a bit confused as to what is required here: just the fact that DVR can work with LBaaS v1? Is that something that should be part of the release notes instead?

I am tempted to mark this invalid for now.
