[RFC V1 4/7] crypto: tcrypt - Add speed test for optimized GHASH computations

From: Megha Dey
Date: Fri Dec 18 2020 - 16:07:45 EST


From: Kyung Min Park <kyung.min.park@xxxxxxxxx>

Add speed test for optimized GHASH computations with vectorized
instructions. Introduce a new test suite to calculate the speed
for this algorithm.
