In linux kernel since version 3.18 (release Date: 2014-12-07)  
SHA-1 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.
