The second series relies on this one and will add bucket mempool driver and related ops. The patch series has generic enhancements suggested by Olivier. Basically it adds driver callbacks to calculate required memory size and to populate objects using provided memory area. It allows to remove so-called capability flags used before to tell generic code how to allocate and slice allocated memory into mempool objects. Clean up which removes get_capabilities and register_memory_area is not strictly required, but I think right thing to do. Existing mempool drivers are updated. rte_mempool_populate_iova_tab() is also deprecated in v2 as agreed in [2]. Unfortunately it requires addition of -Wno-deprecated-declarations flag to librte_mempool since the function is used by deprecated earlier rte_mempool_populate_phys_tab(). If the later may be removed in the release, we can avoid addition of the flag to allow usage of deprecated functions. A new patch is added to the series in v3 to rename MEMPOOL_F_NO_PHYS_CONTIG as MEMPOOL_F_NO_IOVA_CONTIG as agreed in [3]. MEMPOOL_F_CAPA_PHYS_CONTIG is not renamed since it removed in this patchset. It breaks ABI since changes rte_mempool_ops. Also it removes rte_mempool_ops_register_memory_area() and rte_mempool_ops_get_capabilities() since corresponding callbacks are removed. Internal global functions are not listed in map file since it is not a part of external API.
