I know this is just copied, but these have no effect on validation. I 
assume what they are meant to be is these are the subset of 
ethernet-controller.yaml which are allowed, but that would only work 
with 'additionalProperties: false'. That wouldn't work because we also 
want to users to extend this with custom properties. What's needed here 
is a list of properties not allowed:

disallowed-prop: false

Or we can just allow anything from ethernet-controller.yaml and drop 
this list.
