Previously the selection was solely made at compile-time, meaning it could only be built and run on the same generation of CPU. Adding run-time selection ability means this can be used from distro packages and/or DPDK can be compiled on an older CPU and run on a newer CPU. 2) Adds an optimized CRC implementation based on the AVX512 and VPCLMULQDQ instruction sets. For further details, please see the commit messages of the individual patches. v4: * Fixed build issue when older version of meson is used (0.47.1) * Addressed review comments * remove Intel copyright header from neon CRC file * tidy-up of register initialisation v3: * Re-submitted v2 as encountered problems when originally submitting it. v2: * Added support for run-time selection of optimal architecture-specific CRC, based on v1 review comment. * Added full working AVX512/VPCLMULQDQ support for CRC32-Ethernet and CRC16-CCITT. v1: * Initial version, with incomplete AVX512/VPCLMULQDQ support for CRC32-Ethernet only.
