tools: ynltool: create skeleton for the C command

2025-11-11T11:21:04+00:00

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.
