As described in the docs we have 4 "protocols" or compatibility levels, and each one comes with its own schema, but the more general / legacy schemas are superset of more modern ones: genetlink is the smallest followed by genetlink-c and genetlink-legacy. There is no schema for raw netlink, yet, I haven't found the time.. I don't know enough jsonschema to do inheritance or something but the repetition is not too bad. I hope.
