I think it should be our default type. Explicit length should only 
be picked if there's a clear reason. Too many review cycles wasted
steering people onto correct types...

Now, I'm not sure Pablo merged the sint/uint support into libmnl,
I can share the patches to handle them in iproute2, if that helps.
Or just copy/paste from YNL.

I need to find the courage to ask you how we can start using YNL
in iproute2, I really worry that we're not getting CLI tools written
for new families any more :(
