From c4a89279086e9c98eba659d7665b1732e0d5e3e3 Mon Sep 17 00:00:00 2001 From: "Hook, Gary" Date: Tue, 9 Jul 2019 15:07:22 +0000 Subject: crypto: ccp - Add a module parameter to specify a queue count Add a module parameter to limit the number of queues per CCP. The default value (nqueues=0) is to set up every available queue on each device. The count of queues starts from the first one found on the device (which varies based on the device ID).
