Subject: [PATCH net-next 00/13] tools: ynl: more docs and basic ethtool support

I got discouraged from supporting ethtool in specs, because
generating the user space C code seems a little tricky.
The messages are ID'ed in a "directional" way (to and from
kernel are separate ID "spaces"). There is value, however,
in having the spec and being able to for example use it
in Python.

After paying off some technical debt - add a partial
ethtool spec. Partial because the header for ethtool is almost
a 1000 LoC, so converting in one sitting is tough. But adding
new commands should be trivial now.

Last but not least I add more docs, I realized that I've been
sending a similar "instructions" email to people working on
new families. It's now intro-specs.rst.

Jakub Kicinski (13):
  tools: ynl-gen: prevent do / dump reordering
  tools: ynl: move the cli and netlink code around
  tools: ynl: add an object hierarchy to represent parsed spec
  tools: ynl: use the common YAML loading and validation code
  tools: ynl: add support for types needed by ethtool
  tools: ynl: support directional enum-model in CLI
  tools: ynl: support multi-attr
  tools: ynl: support pretty printing bad attribute names
  tools: ynl: use operation names from spec on the CLI
  tools: ynl: load jsonschema on demand
  netlink: specs: finish up operation enum-models
  netlink: specs: add partial specification for ethtool
  docs: netlink: add a starting guide for working with specs
