Use this_cpu_inc(vport->percpu_stats->packets) here?

Lots of network drivers use u64_stats_sync infrastructure for statistics

So they would all have an advantage from the patch.

I will try to do the optimizing next time in another patchset which not included
in this series patchset.

I will submit v3 version of this series after testing today.

Thanks
