d239c85197
The following patch adds the concept of allowed address pairs. This allows one to add additional ip/mac address pairs on a port to allow traffic that matches those specified values. This is useful in order to leverage dataplane failover mechanisms like vrrp. This patch adds support for the NVP plugin, the OVS plugin, and Ml2.
