I certainly will test it in a few different network circumstances,
This version uses the same principle as the AVX2 version by scheduling the
operations for two block pairs in parallel. It benefits from the AVX-512VL
rotate instructions and the more efficient partial block handling using
"vmovdqu8", resulting in a speedup of the raw block function of ~20%.
In the quest for pushing the limits of chacha20 encryption for both IPsec
and Wireguard, this small series adds AVX-512VL block functions. The VL
variant works on 256-bit ymm registers, but compared to AVX2 can benefit
from the new instructions.

This variant is similar to the AVX2 version, but benefits from the AVX-512
rotate instructions and the additional registers, so it can operate without
any data on the stack. It uses ymm registers only to avoid the massive core
throttling on Skylake-X platforms. Nontheless does it bring a ~30%

Thanks for the offer, no need at this time. But I certainly would
welcome if you could do some (Wireguard) benching with that code to see
if it works for you.
