For Ubuntu I've dropped pre-Pike releases from affected series as a fix for https://bugs.launchpad.net/neutron/+bug/1708092 would be a pre-requisite at least for Ocata. That fix is fairly involved and we would have to evaulate the risk of backporting that to Ocata if in fact any fixes were needed back that far.
