Have you considered putting this earlier up in the output, where the
mark is printed as well?

If you wanted to implement the suggestion above, I think you could do
that by moving this code into xfrm_xfrma_print.
Other than that, LGTM.

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.
