+* librte_mempool: The rte_mempool struct will be changed in 16.07 to
+  facilitate the new external mempool manager functionality.
+  The ring element will be replaced with a more generic 'pool' opaque pointer
+  to allow new mempool handlers to use their own user-defined mempool
+  layout. Also newly added to rte_mempool is a handler index.
+  The existing API will be backward compatible, but there will be new API
+  functions added to facilitate the creation of mempools using an external
+  handler. The 16.07 release will contain these changes.
