No seg id for router port

[Eran Gampel]

The port data is not inserted into the l3_app because it is missing the segmentation id

It seem to be a BUG related to the change of the router type to DVR to support the centralize SNAT

    It seem that this BUG is related to the change of the router type to DVR in order to support the centralize SNAT
    We will need to check if this is a bug in neutron or by design but the
    router port is missing the segmentation id data
    To overcome this is issue we send additional arp notify for each new
    port
    for the router port on the same subnet, this will double the number of
    arp notify RPC messages to the agent messages but this is the only way
    to fix it from outside of neutron
