From 54a13c493f1292215089747b820461a91df7f80e Mon Sep 17 00:00:00 2001 From: "Jay S. Bryant" Date: Fri, 7 Jun 2019 10:07:20 -0500 Subject: [PATCH] Update QoS and add Accuracy Note We discussed at the last mid-cycle that the definition of QoS should be updated to indicate this is for backend QoS support. I have added that clarification with this patch. I have also added a note that this is not an auto-generated matrix and the accuracy should be handled accordingly.
