Hi Jan,

Thanks for the clarification. I also came across patch port as the best
option between ovs Bridges. But, is it possible to use patch ports to an
external OpenFlow bridge? Like one bridge is OVS, other is Lagopus bridge
or LINC bridge? For my use case, I want to send packets from OVS Bridge to
another OpenFlow bridge(like a loopback port) as OVS doesn't support the
functionality I am looking for.
