net: sched: provide per cpu qstat helpers
The per cpu qstats support was added with per cpu bstat support which is currently used by the ingress qdisc. This patch adds a set of helpers needed to make other qdiscs that use qstats per cpu as well. Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: David S.
