[net-next,0/4] ynl: fill in some gaps of ethtool spec

Message

I was trying to fill in the spec while exploring ethtool API for some
related work. I don't think I'll have the patience to fill in the rest,
so decided to share whatever I currently have.

Patches 1-2 add the be16 + spec.
Patches 3-4 implement an ethtool-like python tool to test the spec.

Patches 3-4 are there because it felt more fun do the tool instead
of writing the actual tests; feel free to drop it; sharing mostly
to show that the spec is not a complete nonsense.

The spec is not 100% complete, see patch 2 for what's missing.
I was hoping to finish the stats-get message, but I'm too dump
to implement bitmask marshaling (multi-attr).

Stanislav Fomichev (4):
  ynl: support be16 in schemas
  ynl: populate most of the ethtool spec
  ynl: replace print with NlError
  ynl: ethtool testing tool
