    ML2: ODL driver sets port status
    
    The OpenDaylight mechanism driver does not depend on an L2 agent to
    plug the port. Now that nova waits for notification that the port
    status is ACTIVE, the ML2 driver API is extended so that the mechanism
    driver that binds a port can optionally set the port status, and the
    OpenDaylight mechanism driver uses this to set the port status to
    ACTIVE.

Title:
  ODL ML2 driver doesn't notify active/inactive ports

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  The nova-event-callback blueprint [1] implemented the notifications of
  active/down ports to Nova. Before effectively starting an instance,
  Nova compute waits for a "VIF plugged" notification from Neutron.

  I'm running ODL ML2 driver in a devstack using the master branch and I
  notice that the ODL driver doesn't notify back the Nova API. Hence
  with the default settings, the VM creation always fails.

  As a workaround, set the following parameters in your nova.conf:
  vif_plugging_timeout = 10
  vif_plugging_is_fatal = False

  With this configuration, I'm able to boot and connect to the instances
  but the Neutron ports are always reported as DOWN [2].
