The patchset introuduces IPv6 optimized MFEX profiles with AVX512 which can deliver upto 20% to 30% gain in performance over the existing scalar data-path.
Hashing Optimization are also included which can further improve performance by approximately 10%. The patch also removes the magic numbers for MF bits, packet offsets and packet lenghts. --- v11: - Rebase on top of AVX512 runtime ISA check patch. v10: - Reabse onto Cian Partial AVX512 build patch. v9: - Fix Ubsan un-alinged memory load. v8: - Rename packet offsets defines to aling with packet struct. v7: - Remove magic numbers from AVX512 Profiles. v5: - Add Ipv6 and TCP packet length checks. v4: - rebase to master. - use static key lenghts for different packet types. v3: - rebase to master. v2: - fix the CI build. - fix check-patch for co-author. --- Kumar Amber (4): mfex_avx512: Calculate pkt offsets at compile time. mfex_avx512: Calculate miniflow_bits at compile time. dpif-netdev/mfex: Add AVX512 ipv6 traffic profiles dpif-netdev/mfex: Add ipv6 profile based hashing.
