          SHA-512 secure hash standard (FIPS 180-1/DFIPS 180-2) implemented

          using multi-buffer technique.  This algorithm computes on

          multiple data lanes concurrently with SIMD instructions for

          better throughput.  It should not be enabled by default but

          used when there is significant amount of work to keep the keep

          the data lanes filled to get performance benefit.  If the data

          lanes remain unfilled, a flush operation will be initiated to

          process the crypto jobs, adding a slight latency.
