Re: [PATCH 00/10] crypto: x86_64 - Add SSE/AVX2 ChaCha20/Poly1305 ciphers

Herbert,

I get less constant numbers between different runs when using sec=0,
hence I've used sec=1. Below are the numbers of "average" runs for the
AEAD measuring cycles; I'll use cycles in the individual patch notes in
a v2.

Kind regards
