So I've been looking over Quentin's series just now that sits in my
bucket and it looks fine to me, but merge with this one would probably
end up badly for David. Therefore I'm proposing the following that
should hopefully be fine and work out for Alexander and Jakub/Quentin
as a consensus:

I'm getting the current bpf-next stuff as PR out in a few minutes, so
David can pull this in and therefore net-next will also have the
dependency on nfp for Quentin's series. Then, given this one here
needs another respin anyway, I would suggest to combine the missing
patches from Alexander's series, and get it all out in a single patch
series directly for net-next w/o any interdependency hassle.

Thanks,
Daniel
