I don't think you need to expose this in C. I had to solve this
problem for rtnl because we nested dpll attrs in link info. Please see:

https://github.com/kuba-moo/linux/commit/6faf7a638d0a5ded688a22a1337f56470dca85a3

and look at the change for dpll here (sorry IDK how to link to a line :S)

https://github.com/kuba-moo/linux/commit/00c8764ebb12f925b6f1daedd5e08e6fac478bfd

With that you can add the decode info to the YAML spec for Python et al.
but there's no need do duplicate the values. Right now this patch
generates a bunch of "missing kdoc" warnings.

Ima start sending those changes after the net -> net-next merge,
some of the prep had to go to net :(
