It would be better if it can be in 18.11. Upstream OVS will point at a release tarball, and at present an 18.11.1 release is not due until mid-January. If it's too late for 18.11, alternatively we could do an earlier 18.11.1 release. > Once in the next-virtio tree, I'll send it to sta...@dpdk.org. > > Regards, > Maxime > >> P.S.
