It seem always:
        memset(&link_ksettings, 0, sizeof(link_ksettings));
        err = dev->ethtool_ops->get_link_ksettings(dev, &link_ksettings);

do we really need:
       ethtool_link_ksettings_zero_link_mode(cmd, supported);
       ethtool_link_ksettings_zero_link_mode(cmd, advertising);
       cmd->base.phy_address   = 0;
?
