--- fixes: - | `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 `_ 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.
