    Description

      Todays modern processors contain instruction sets that can be used to accelerate CRC32C. SSE4.2 introduced a new crc32c instruction but not all processors contain that instruction but many do support pclmulqdq. This work
      back ports from the linux 3.10 kernels support of crc32c accelerated by pclmulqdq.
