Merge branch 'tools-ynl-gen-code-gen-improvements-before-ethtool'
Jakub Kicinski says:
====================
tools: ynl-gen: code gen improvements before ethtool
I was going to post ethtool but I couldn't stand the ugliness
of the if conditions which were previously generated.
So I cleaned that up and improved a number of other things
ethtool will benefit from.
