Thanks for the series Harry, it looks ok tom myself, have tested locally on a few machines and with Travis for both master and Branch 2.14. https://travis-ci.org/github/istokes/ovs/builds/715140114 https://travis-ci.org/github/istokes/ovs/builds/715139732 I've pushed this to master and as it would be an issue for 2.14 (and the patches are minor) I've pushed there too. WRT backporting beyond that I'm open to discussion, I guess the same issue could occur right? But as there was no AVX512 code previous to 2.14 it wouldn't have been visible?
