It also shortens the code and cleans it up a little. The base requirement for using the SSE code path has been pushed up to SSE4.1 from SSE3, due to the use of the blend instruction. The instructio= n set level is now checked at runtime as part of the driver selection proce= ss Bruce Richardson (3): i40e: require SSE4.1 support for vector driver i40e: improve performance of vector PMD i40e: simplify SSE packet length extraction code drivers/net/i40e/Makefile | 6 ++++ drivers/net/i40e/i40e_rxtx_vec.c | 59 ++++++++++++++--------------------= ------ 2 files changed, 27 insertions(+), 38 deletions(-) --=20 2.5.5
