40 * Customizer for enabling/disabling ACLs for given sub-interface (as defined in ietf-acl model).
42 * The customizer assumes it owns classify table management for sub-interfaces where ietf-acl container is present.
43 * Using low level classifier model or direct changes to classify tables in combination with ietf-acls are not supported
44 * and can result in unpredictable behaviour.
