I don't know what it will buy you.

Why don't you submit separate patch for below hunk, after your EOPNOTSUPP in ethtool_op_set_flags get accepted.

BTW, thanks of this fix.

remove such usage of ethtool_op_set_flags() for my furher patches, where
I plan to add return EOPNOTSUPP to ethtool_op_set_flags().
