v3 changes: move while after case 0 add context about duff's device and why we use while loop in the commit message
v2 changes: unroll the loop in rte_pktmbuf_alloc_bulk to help the performance For symmetric rte_pktmbuf_free_bulk, if the app knows in its scenarios their mbufs are all simple mbufs, i.e meet the following requirements: * no multiple segments * not indirect mbuf * refcnt is 1 * belong to the same mbuf memory pool, it could directly call rte_mempool_put to free the bulk of mbufs, otherwise rte_pktmbuf_free_bulk has to call rte_pktmbuf_free to free the mbuf one by one. This patchset will not provide this symmetric implementation.
