These instructions can be used in the data path to enhance the per-core performance of packet processing. Comparing with the existing implementation, this path set introduces some AVX512 instructions into the iavf data path, and we get a better per-code throughput. v2: Update meson.build. Repalce the deprecated 'buf_physaddr' by 'buf_iova'. v3: Fix compile errors. v4: Fix wrong info in commnets. Trivial adjustment of the arrangement. v5: Support "max SIMD bitwidth". v6: Rework meson build to fix compile issue for AVX512BW.
