-/**
- * @deprecated
- * Create a new mempool named *name* in memory.
- *
- * The pool contains n elements of elt_size. Its size is set to n.
- * This function uses ``memzone_reserve()`` to allocate the mempool header
- * (and the objects if vaddr is NULL).
- * Depending on the input parameters, mempool elements can be either allocated
- * together with the mempool header, or an externally provided memory buffer
- * could be used to store mempool objects. In later case, that external
- * memory buffer can consist of set of disjoint physical pages.
- *
- * @param name
- * The name of the mempool.
- * @param n
- * The number of elements in the mempool. The optimum size (in terms of
- * memory usage) for a mempool is when n is a power of two minus one:
- * n = (2^q - 1).
- * @param elt_size
- * The size of each element.
- * @param cache_size
- * Size of the cache. See rte_mempool_create() for details.
- * @param private_data_size
- * The size of the private data appended after the mempool
- * structure. This is useful for storing some private data after the
- * mempool structure, as is done for rte_mbuf_pool for example.
- * @param mp_init
- * A function pointer that is called for initialization of the pool,
- * before object initialization. The user can initialize the private
- * data in this function if needed. This parameter can be NULL if
- * not needed.
- * @param mp_init_arg
- * An opaque pointer to data that can be used in the mempool
- * constructor function.
- * @param obj_init
- * A function called for each object at initialization of the pool.
- * See rte_mempool_create() for details.
- * @param obj_init_arg
- * An opaque pointer passed to the object constructor function.
- * @param socket_id
- * The *socket_id* argument is the socket identifier in the case of
- * NUMA. The value can be *SOCKET_ID_ANY* if there is no NUMA
- * constraint for the reserved zone.
- * @param flags
- * Flags controlling the behavior of the mempool. See
- * rte_mempool_create() for details.
- * @param vaddr
- * Virtual address of the externally allocated memory buffer.
- * Will be used to store mempool objects.
- * @param iova
- * Array of IO addresses of the pages that comprises given memory buffer.
- * @param pg_num
- * Number of elements in the iova array.
- * @param pg_shift
- * LOG2 of the physical pages size.
- * @return
- * The pointer to the new allocated mempool, on success. NULL on error
- * with rte_errno set appropriately. See rte_mempool_create() for details.
