From c14003f09068711c8f1ad9cb89b5520b3579e563 Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Thu, 20 Sep 2018 21:39:22 +0300 Subject: [PATCH] IB/mlx5: Set uid as part of SQ commands Set uid as part of SQ commands so that the firmware can manage the SQ object in a secured way. The uid for the destroy command is set by mlx5_core. This will enable using an SQ that was created by verbs application to be used by the DEVX flow in case the uid is equal.
