Based on past discussions it seems like integration of YNL into
iproute2 is unlikely. YNL itself is not great as a C library,
since it has no backward compat (we routinely change types).

Most of the operations can be performed with the generic Python
CLI directly. There is, however, a handful of operations where
summarization of kernel output is very useful (mostly related
to stats: page-pool, qstat).

Create a command (inspired by bpftool, I think it stood the test
of time reasonably well) to be able to plug the subcommands into.
