I imagine it happening the other way around. Updated drivers would
implement only the devlink interface. A compat layer would be introduced
to redirect from ethtool calls into devlink to gather information (like
fw version and other stuff which is currently in ethtool).
This approach would provide a single and complete interface between
driver and kernel and it would also maintain exinsting ethtool
interface.
