This was reported just yesterday: http://openvswitch.org/pipermail/discuss/2015-September/018714.html I'm assuming that this is with the out of tree OVS kernel module. In that case, the change is in OVS 2.4 and shouldn't be a difference between Linux 3.14 and 3.18. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
