Public bug reported:

The _device_to_port_id method in ML2 accepts either an interface name, a
port UUID, or a MAC address and returns the corresponding port ID.

The part that takes an interface name currently only works if the
interface prefix is 'tap'. This is broken in the cases where security
group filtering is used ('qvo' prefix) and snat interfaces ('sg-').

This is okay in the cases where the external id is loaded directly into
the database, but it doesn't work for vswitches that don't have OVSDB or
when scripts have re-added the interface to the vswitch without the
external ID.
