Hi Luke,

I've added the [third-party] tag as well to ensure this catches the broadest segment of relevant people. Probably a stupid question from me - are any modifications to upstream Open vSwitch required to support Snabb?

Thanks,

Steve

Have you already attempted to solicit some core reviewers in Nova and Neutron with an
