Bug Description
(amuller) editing bug report based on comment 7:
Dropping flows on the the physical bridges causes networking to drop. It's one of the two places that still causes networking to drop when OVS agent is restarted. The other is that the patch port between br-int and br-tun is being deleted and rebuilt during startup.
Original bug description contained intent to set cookie on physical bridges for consistency purposes.
In other words, with absence of cookies, flows can't be removed properly, so for kilo/liberty version that lead to stale flows remaining in OVS and disrupting the network.
