> Introduce a new api to retrieve per queue statistics from the drivers.
> The api objectives:
> - easily add some common per queue statistics and have it exposed
> through the user xstats api while the user stats api is left untouched
> - remove the limitations on the per queue statistics count (inherited
> from ixgbe) and avoid recurrent bugs on stats array overflow
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
