AES-GCM enabled with AVX512 vAES and vPCLMULQDQ.
Vectorized 'stitched' encrypt + ghash implementation of AES-GCM enabled
with AVX512 vAES and vPCLMULQDQ instructions (available starting Intel's
IceLake micro-architecture).
The performance details for representative IceLake Server and Client
platforms are shown below
