Hi Ferruh,

What about the patch?

I also support dropping ethtool for ixgbe and i40e, but to save generic
ethtool_ops
with .get_link implementation, because it's an essential function that
works correctly
after proper implementation of carrier status that was merged into 18.11.

Also, other ethtool operations may be implemented in a driver-independent
way using
the same concept as for netdev_ops.
