midonet ml2 mech driver does not update port status properly

[Ryu Ishimoto]

ML2 sets the port status to 'DOWN' by default. For logical ports such as router interface and gateway port, the statuses should be set to ACTIVE upon success of the Neutron->MidoNet translation. In the future, MidoNet will support a better mechanism to update the status (either by the MidoNet cluster updating the status field or the plugin querying the cluster for the status). For now, set it to ACTIVE since the DOWN status is more likely to give the wrong impression of the reality.

    devstackgaterc: Skip test_router_interface_status for ML2

    We currently never update status of purely logical ports
    (in MidoNet term, interior ports) like router interfaces.
    It ought to be fixed, but in case of ML2 it needs some mechanism
    in ML2 driver api. [1]
    For now, just skip the relevant test.

Just wondering if anyone is working on this. This is the number 1 confusion for our users and I'd really like a fix.

Even if that fix was to say it was ACTIVE all the time as opposed to DOWN all the time.

[YAMAMOTO Takashi (yamamoto)]

Sam,

to fix it properly, there needs an api for MDs to report port status.
eg. https://review.openstack.org/#/c/336068/
it will likely be one of the ML2 topics for the next PTG.

i occasionally see reports about this. maybe it's more important for users than i thought.
