Thanks, I have made preliminary backports to the relevant branches and am running travisci to see if the tests pass. https://travis-ci.org/horms2/ovs/builds/511479533 https://travis-ci.org/horms2/ovs/builds/511482871 https://travis-ci.org/horms2/ovs/builds/511482977 https://travis-ci.org/horms2/ovs/builds/511482911 https://travis-ci.org/horms2/ovs/builds/511482945 From my point of view travisci passing is a base requirement for applying patches, in particular backports to released versions. _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
