    Use ovs_port_updated event to update ofport and mac

    Currently, df apps use ovs idl to query the mac of ovs Interface.
    ovs_port_updated event was introduced in [1]. And there is already an
    ovs Interface object in the event. So, df apps can just get mac address
    from that event. This can save a query from ovs db, and also stop abuse
    of ovs idl.
