  scalability the statistic counters should be per-CPU and we should stop using
  atomic operations for them however we have to remain the counters and atomic
  operations.
+ Scalability
+ -----------
+  - Per-CPU rtcaches (used in say IP forwarding) aren't scalable on multiple
+    flows per CPU
+  - ipsec(4) isn't scalable on the number of SA/SP; the cost of a look-up
+    is O(n)
