[Bug 1735248] Re: HW offload support for set actions

[James Page]

Simon; if these patches will be included in ovs 2.9.x we're all good for
Ubuntu Bionic; 2.9.0 should be the 18.04 release version of ovs (based
on currently plans for both Ubuntu and OVS).

I'd rather not pull them into Bionic as distro patches ontop of 2.8, but
we could pull in a 2.9.x snapshot as soon as OVS create a branch.
