From: Lazaros Koromilas <l...@nofutznetworks.com>
This commit introduces the API calls:
rte_mempool_generic_put(mp, obj_table, n, is_mp)
rte_mempool_generic_get(mp, obj_table, n, is_mc)
Deprecates the API calls:
rte_mempool_mp_put_bulk(mp, obj_table, n)
rte_mempool_sp_put_bulk(mp, obj_table, n)
rte_mempool_mp_put(mp, obj)
rte_mempool_sp_put(mp, obj)
rte_mempool_mc_get_bulk(mp, obj_table, n)
rte_mempool_sc_get_bulk(mp, obj_table, n)
rte_mempool_mc_get(mp, obj_p)
rte_mempool_sc_get(mp, obj_p)
We also check cookies in one place now.
