[dpdk-dev] [PATCH 0/4] optimize and use armv8 CRC extensions for hash library

[Jerin Jacob]

- This patch set has the changes required for optimised hash library usage in arm64 perspective
- Tested on Juno and Thunderx boards
- Tested and verified the changes with following DPDK unit test cases
        hash_functions_autotest
        hash_autotest
        hash_perf_autotest
        hash_scaling_autotes
-   Created the new xgene1 machine target to address the difference
    in optional armv8-a CRC extension availability compared to
    default armv8-a machine target(enabled CRC extension by default)
-  Supersededs the [dpdk-dev] [PATCH] hash: replace libc memcmp with
 optimized memory compare functions for arm64 patch


Jerin Jacob (4):
  hash: replace libc memcmp with optimized memory compare functions for
    arm64
  hash: implement rte_hash_crc_* based on armv8-a CRC32 instructions
  hash: select hash function as CRC if armv8-a CRC extension available
  mk: add xgene1 machine target based on armv8-a
