[dpdk-dev] [PATCH v3 2/2] net: add support for AVX512/VPCLMULQDQ based CRC

This patch enables the optimized calculation of CRC32-Ethernet and CRC16-CCITT using the AVX512 and VPCLMULQDQ instruction sets. This CRC implementation is built if the compiler supports the required instruction sets. It is selected at run-time if the host CPU, again, supports the required instruct
