I assumed we would get a notification when the status changes, which would allow us to mark it as invalid. If we don't get the right kind of notification to invalidate our IPv4/v6 address caches, then we either shouldn't cache them at all or subscribe to the right kind of notification. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
