[dpdk-dev] [PATCH] rte_mbuf: scattered pktmbufs freeing optimization
From: "vadim.suraev at gmail.com"
new function - rte_pktmbuf_free_bulk makes freeing long
scattered (chained) pktmbufs belonging to the same pool
more optimal using rte_mempool_put_bulk rather than calling
rte_mempool_put for each segment.
Inlike rte_pktmbuf_free, which calls rte_pktmbuf_free_seg,
this function calls __rte_pktmbuf_prefree_seg. If non-NULL
returned, the pointer is placed in an array. When array is
filled or when the last segment is processed, rte_mempool_put_bulk
is called. In case of multiple producers, performs 3 times better.
