From c3a536056374ef8412c7ffa13790303ec02d8f46 Mon Sep 17 00:00:00 2001 From: Jon Maxwell Date: Wed, 22 Nov 2017 16:08:17 +1100 Subject: crypto: cryptd - Add cryptd_max_cpu_qlen module parameter Make the cryptd queue length configurable. We recently had customer where this needed to be tuned to accommodate the aesni_intel module and prevent packet drop.
