Skip ovnkube private interface when getting host IP
02f6d95 
During live migration, the SDN control-plane may run on ovnkube nodes.
So we need to ignore the ovnkube interface.

Add flows that allow openshift-sdn to connect to ovnkube
b19bbb0 
During live migration, openshift-sdn nodes will be connected to
ovnkube network as hybrid overlay nodes. The VXLAN packets from
ovnkube node have the same dest_MAC as the both the inner and
outer MAC with the MAC address of the physical interface. In order
to forward the packet to the pod, we swap the inner MAC to the
real MAC of the pod in table 10.
