Thanks Roi, Thanks Vlad, these changes look good to me. I have put them into Travis-CI, as per my usual process, to see if it flags anything. https://travis-ci.org/github/horms2/ovs/builds/693802765 https://travis-ci.org/github/horms2/ovs/builds/693800395 _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
