 * librte_meter: The API will change to accommodate configuration profiles.
   Most of the API functions will have an additional opaque parameter.
+
+* ring: The alignment constraints on the ring structure will be relaxed
+  to one cache line instead of two, and an empty cache line padding will
+  be added between the producer and consumer structures. The size of the
+  structure and the offset of the fields will remain the same on
+  platforms with 64B cache line, but will change on other platforms.
