Not sure what you mean by inserting a static flow to a desired port, but
I've tried to do this earlier, though without any success:
ovs-ofctl add-flow br-eth0 in_port=4,actions=output:6 (4 is br-mgmt, 6 is
eth0)

Seems like the reply doesn't make it to eth0 on node-6. I've tried running
tcpdump on eth6 (VF), but no packages are being captured.
