+
+* The second argument of rte_pktmbuf_pool_init(mempool, opaque) is now a
+ pointer to a struct rte_pktmbuf_pool_private instead of a uint16_t
+ casted into a pointer. Backward compatibility is preserved when the
+ argument was NULL which is the majority of use cases, but not if the
+ opaque pointer was not NULL, as it is not technically feasible. In
+ this case, the application has to be modified to properly fill a
+ rte_pktmbuf_pool_private structure and pass it to
+ rte_pktmbuf_pool_init().
+
+* A simpler helper rte_pktmbuf_pool_create() can be used to create a
+ packet mbuf pool. The old way using rte_mempool_create() is still
+ supported though and is still used for more specific cases.
