AVX512 instructions is supported by more and more platforms. 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".

Wenzhuo Lu (3):
  net/iavf: enable AVX512 for legacy RX
  net/iavf: enable AVX512 for flexible RX
  net/iavf: enable AVX512 for TX
