This patchset introduces miniflow extract Infrastructure changes
which allows user to choose different type of ISA based optimized
miniflow extract variants which can be user choosen or set based on 
packets studies automatically by OVS using different commands.
The Infrastructure also provides a way to check the correctness of
different ISA optimized miniflow extract variants against the scalar
version.

Harry van Haaren (4):
  dpif/stats: add miniflow extract opt hits counter
  dpdk: add additional CPU ISA detection strings
  dpif-netdev/mfex: Add AVX512 based optimized miniflow extract
  dpif-netdev/mfex: add more AVX512 traffic profiles

Kumar Amber (7):
  dpif-netdev: Add command line and function pointer for miniflow
    extract
  dpif-netdev: Add auto validation function for miniflow extract
  dpif-netdev: Add study function to select the best mfex function
  docs/dpdk/bridge: add miniflow extract section.
  dpif-netdev: Add configure to enable autovalidator at build time.
  dpif-netdev: Add packet count and core id paramters for study
  test/sytem-dpdk: Add unit test for mfex autovalidator
