From: Antoni Segura Puimedon <toni@xxxxxxxxxxxx>
Midonet is an opensource virtual networking that over lays the IP
network between hypervisors. Currently, such networks can be made
with the openvswitch virtualport type. With this patch, one will
be able to setup such configurations by binding vNICs to Midonet
overlay ports.
