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.
* The rte_mempool allocation will be changed in 16.07:
allocation of large mempool in several virtual memory chunks, new API
to populate a mempool, new API to free a mempool, allocation in
anonymous mapping, drop of specific dom0 code. These changes will
induce a modification of the rte_mempool structure, plus a
modification of the API of rte_mempool_obj_iter(), implying a breakage
of the ABI.
