+* ABI change is planned for the rte_mempool structure to allow mempool
+  cache support to be dynamic depending on the mempool being created
+  needing cache support. Saves about 1.5M of memory per rte_mempool structure
+  by removing the per lcore cache memory. Change will occur in DPDK 16.07
+  release and will skip the define RTE_NEXT_ABI in DPDK 16.04 release. The
+  code effected is app/test/test_mempool.c and librte_mempool/rte_mempool.[ch].
+  The rte_mempool.local_cache will be converted from an array to a pointer to
+  allow for dynamic allocation of the per lcore cache memory.
