Nogah says:

Until now we had stats functions return SW statistics. However, it makes
a lot of sense to return HW stats as default. The existing apps count with
having the defaults stats complete, but that is not true now as the offloaded
forward traffic is not visible there.

If user wants to know real SW stats, this patchset provides way to get
it as well.
