From 430ae0d5a3ce1350375690cb6ab29ab6fae4a9ac Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Thu, 20 Sep 2018 21:35:23 +0300 Subject: [PATCH] net/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. That will enable using an SQ that was created by verbs application to be used by the DEVX flow in case the uid is equal.
