Background: After preliminary discussion with John (Zhihong) and Tim from Intel it was decided that it would be beneficial to use AVX/SSE intrinsics for memcmp similar to memcpy that had been implemeneted. In addition, we decided to use librte_hash as a test candidate to test both functionality and performance.
Further discussions lead to complete functionality implementation of memory comparison and v3 code reflects that. Test was conducted on Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, Ubuntu 14.04, x86_64, 16GB DDR3 system.
