Previous: http://mails.dpdk.org/archives/dev/2019-September/143910.html Patch 1: fix Tx halt when no recv packets (Xiaolong Ye) Patch 2: support pinning of IRQs v1 -> v2: * Change enum format to match coding style * Change some variables to const * Re-order arguments in functions * Do not duplicate driver string in generate_search_idx * Check if driver handler function ptr is !NULL before using * Check return value of fwrite * Use rte_memcpy Patch 3: enable support for unaligned umem chunks v1 -> v2: * Take mbuf alloc out of reserve_fill_queue * Free correct mbuf on reserve fail for tx The performance of the new zero copy implementation was measured to be within 5% of the previous zero copy implementation, generally with an improvement observed for single-core (with need wakeup) and multiple-PMD test cases.
