The bundle requests aren't supported yet. When they are, though, it's pretty important to handle general-purpose rollback. Jarno has done some preliminary work on bundle support, so I'm bringing him into the conversation to share his thoughts. Hardware support isn't a priority because no one has ever contributed support for a hardware platform. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
