    Don't add arp responder for non tunnel network port

    When the vlan and vxlan both exist in env, and l2population
    and arp_responder are enabled, if we update a port's ip address
    from vlan network, there will be arp responder related flows
    added into br-tun, this will cause too many arp reply for
    one arp request, and vm connections will be unnormal.
