[dpdk-dev] [PATCH] hash: optimize the softrss computation

2017-08-22 Thread Yangchao Zhou
Use rte_bsf32 and fast bit unset operation to optimize the softrss computation. The following measurements shows improvement over the default softrss computation function. tuple lens old(cycles) new(cycles) 31225 337 93743 992 Signed-off-by: Yangchao Zhou
