Subject: [PATCH mlx5-next v1 6/7] net/mlx5: Set uid as part of DCT commands
Date: Thu, 20 Sep 2018 21:35:25 +0300	[thread overview]
Message-ID: <20180920183526.13995-7-leon@kernel.org> (raw)
In-Reply-To: <20180920183526.13995-1-leon@kernel.org>

From: Yishai Hadas <yishaih@mellanox.com>

Set uid as part of DCT commands so that the firmware can manage the
DCT object in a secured way.

That will enable using a DCT that was created by verbs application
to be used by the DEVX flow in case the uid is equal.
