From: Benjamin Poirier <bpoir...@suse.com> Some statistics passed to ethtool are garbage because e1000e_get_stats64() doesn't write them, for example: tx_heartbeat_errors. This leaks kernel memory to userspace and confuses users.
Do like ixgbe and use dev_get_stats() which first zeroes out rtnl_link_stats64.
