I think for sysadmins in general (not OVS) use case I would work
with Jesper and Toke. They seem to be working on this specific
problem.

We're definitely thinking about how we can make "XDP magically speeds up
my network stack" a reality, if that's what you mean. Not that we have
arrived at anything specific yet...

And yeah, I'd also be happy to discuss what it would take to make a
native XDP implementation of the OVS datapath; including what (if
anything) is missing from the current XDP feature set to make this
feasible. I must admit that I'm not quite clear on why that wasn't the
approach picked for the first attempt to speed up OVS using XDP...
