I meant the rtnetlink link statistics exposed through ndo_get_stats64(),
i.e. struct rtnl_link_stats64.

The benefit I had in mind was coverage for userspace using the netdev
qstats generic-netlink interface, so that it could query r8169 through
the same qstats path as drivers which already implement netdev_stat_ops.

That said, it does not expose additional driver-specific information.

Agreed, I'll drop this version. Thanks for the review.
