Comment 9 for bug 1969615

So flows look the same for both 2.15 and 2.16 (no surprise here), just that in 2.16 case this weird ofport 7 appears out of nowhere according to vswitchd log, and in fact there's no such ofport on the bridge.

Also flow counters are zero for 2.16 case:

cookie=0xb722108b439955c3, duration=81.938s, table=0, n_packets=0, n_bytes=0, idle_age=81, priority=0 actions=resubmit(,60)

for 2.15 we see packets:

cookie=0xb722108b439955c3, duration=631.481s, table=0, n_packets=35, n_bytes=2870, idle_age=20, priority=0 actions=resubmit(,60)

Not sure it's a neutron issue, probably openvswitch folks could point some ways to debug.
