    ML2 additions to support DVR

yongsheng gong 2014-06-25: The implementation heavily relies on ovs, which does not fit with ML2 spirits. In ML2 spirit, we are promising to allow linux bridge, ovs, and even other access tech to work together. So I think we should think a little longer the solution.
