CCE stats are reported across rings today. Since HKv2 is a SMP, it creates the possibility of missing stats when two or more CPUs are updating the counters for the same protocol type. In order to avoid this, we can either use locks or store stats on a per-CPU basis. Since tagging happens on the core data path, locks are not preferred. Instead, we use a per-ring counter, since each CPU operates on a REO ring. Exception packets today go to Ring-0 (also normal rx Reo-0 go to Ring-0). Hence tags are maintained separately for exception ring as well. Change-Id: Ib01934619fb026bf64a8ac998eaec2d4df7f5a6e CRs-Fixed: 2438143
