Subject: [PATCH mlx5-next 04/25] net/mlx5: Set uid as part of SQ commands
From: Yishai Hadas <yishaih@...lanox.com>
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.
