Merge branch 'tools-ynl-decode-link-types-present-in-tests'

Jakub Kicinski says:

====================
tools: ynl: decode link types present in tests

Using a kernel built for the net selftest target to run drivers/net
tests currently fails, because the net kernel automatically spawns
a handful of tunnel devices which YNL can't decode.

Fill in those missing link types in rt_link. We need to extend subset
support a bit for it to work.
