Other than that, LGTM. Acked-by: Lorenzo Colitti <lorenzo@google.com> Steffen - what's the status of the set_mark patches? Are you holding them until the tree opens again? If so, then once they go in, we can just make "set-mark" behave the same as "output-mark" in the iproute2 code, and add support for the mask as well.

It is time to convert xfrm to json output.

Are you holding > them until the tree opens again? Yes, I hold them back until after v4.18-rc1 is released and the -next trees open again. But I plan to do a RFC version this week, so that everybody knows about the plan we have.
