`1942329 <https://bugs.launchpad.net/neutron/+bug/1942329>`_
Port binding logic for direct-physical ports has been extended to allow
providing the MAC address of the physical device via the binding profile.
If it is provided then Neutron overwrites the value of the
``device_mac_address`` field of the port object in the database with the
value from the active binding profile.
If there are ports bound before `the nova side of this fix is depolyed
<https://review.opendev.org/c/openstack/nova/+/829248>`_ then the VM using
the port needs to be moved or the port needs to be detached and re-attached
to force nova to provide the MAC address of the direct-physical port in the
port binding.
