        this particular interface.  An empty octet string indicates
        that all frames forward at normal priority, regardless of the
        user priority.  Each octet in a non-empty string defines a
        user priority which receives expedited forwarding treatment.
        Ethernet LAN interfaces can be configured with expedited user
        priorities.  All other types of interfaces must always be
        configured with empty expedited priority strings."
