+      Exposes the ``network_interface`` field of the Node resource to the REST
+      API, raising the API maximum version to 1.20. This field is the network
+      interface to use for a node. Its possible values are from the
+      configuration option ``[DEFAULT]enabled_network_interfaces``. Note that
+      the value of this option must be the same on all the ironic-conductor and
+      ironic-api service nodes.
