[RFE] Provide Port Binding Information for Manila Share Server Live Migration

[Maurice Escher]

Hi,

similar to Nova, where this feature is described by https://review.opendev.org/c/openstack/neutron-specs/+/309416/ and implemented around https://bugs.launchpad.net/neutron/+bug/1580880, there is a Share Server Live Migration feature in Manila (see https://review.opendev.org/c/openstack/manila-specs/+/735970), that would benefit of this port binding extension.

If the migration target is in a different network segment, Manila needs to be able to do the port binding before the actual migration starts. This is relevant for the neutron bind driver in manila, that was added to support hierarchical port binding in https://review.opendev.org/c/openstack/manila-specs/+/315985

Best regards,
Maurice

    allow manila ports to do multiple port binding for ML2

    Similar to Nova live migration
    (see https://review.opendev.org/c/openstack/neutron/+/414251/74/neutron/plugins/ml2/plugin.py#2005)
    Manila wants to do share live migration, and needs to modify its ports in a
    similar way: issue port binding upfront to determine the segmentation id in
    the target network segment.
