Subject: [PATCH mlx5-next 03/25] net/mlx5: Set uid as part of RQ commands
Date: Mon, 17 Sep 2018 14:03:56 +0300 [thread overview]
Message-ID: <20180917110418.18937-4-leon@kernel.org> (raw)
In-Reply-To: <20180917110418.18937-1-leon@kernel.org>
From: Yishai Hadas <yishaih@mellanox.com>
Set uid as part of RQ commands so that the firmware can manage the
RQ object in a secured way.
That will enable using an RQ that was created by verbs application
to be used by the DEVX flow in case the uid is equal.
