Inside it contains two code-paths – one uses mostly 256 bit instruction/registers and can process up to 16 flows in parallel. second uses 512 bit instruction/registers over majority of places and can process up to 32 flows in parallel. These internal code-path selection is done internally based on input burst size and is totally opaque to the user. On my SKX box test-acl shows ~20-65% improvement (depending on rule-set and input burst size) when switching from AVX2 to AVX512 classify algorithms. Note that this change introduce a formal ABI incompatibility with previous versions of ACL library. TODO list: - Deduplicate 8/16 code paths - Update default algorithm selection - Update docs These patch series depends on: https://patches.dpdk.org/patch/70429/ to be applied first.
