I have looked at more drivers.
I will try to handle the case where drivers are only keeping tracks of per
q stats and aggregate then when called by .stats_get.
The drivers with hw counters would need both .stats_get and per q
functions, so I need to accomodate with this.
v2 rfc for next week unless someone totally disagrees with the approach
before :-)
