What about the patch?
I also support dropping ethtool for ixgbe and i40e, but to save generic
with .get_link implementation, because it's an essential function that
after proper implementation of carrier status that was merged into 18.11.
Also, other ethtool operations may be implemented in a driver-independent
the same concept as for netdev_ops.
