> enic_get_ethtool_stats() Looknig merely at this shows the real problem. We don't propagate and handle errors for this method. And that's what we should fix, making the get_ethtool_stats() method return an integer error. Then ethtool_get_stats() should return any non-zero value provided by ops->get_ethtool_stats() and not attempt to copy any bytes of 'data' to userspace in that case.
