Hmm, not sure if that's ever going to be the case. Even with drivers
that are going to expose standardized forms of counters, I'm not sure
it's going to be nice to remove them from ethtool -S. Testing teams all
over the world have scripts that grep for those. Unfortunately I think
ethtool -S will always remain a dumping ground of hell, and the place
where you search for a counter based on its name from the hardware block
guide as opposed to its standardized name/function. And that might mean
there's no reason to not accept Oleksij's patch right away. Even if he
might volunteer to actually follow up with a patch where he exposes the
.ndo_get_stats64 from DSA towards drivers, as well as implements
.ndo_has_offload_stats and .ndo_get_offload_stats within DSA, that will
most likely be done as separate patches to this one, and not change in
any way how this patch looks.
