From e4e245ad031f82795a2512cb6d3167c824c6fe81 Mon Sep 17 00:00:00 2001 From: Wojciech Ziemba Date: Thu, 11 Jun 2020 22:14:48 +0100 Subject: [PATCH] crypto: qat - send admin messages to set of AEs Update the logic that sends admin messages to be able to target a subset of Acceleration Engines (AEs) in the device. In future not all admin messages need to be sent to all the AEs.
