[PATCH rdma-next 18/25] IB/mlx5: Set uid as part of DCT commands

From: Leon Romanovsky <leon@kernel.org>
Date: 2018-09-17 16:32:39
Also in: linux-rdma
Subsystem: infiniband subsystem, mellanox mlx5 ib driver, the rest · Maintainers: Jason Gunthorpe, Leon Romanovsky, Linus Torvalds

From: Yishai Hadas <redacted>

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

The uid for the destroy and drain commands are set by mlx5_core.

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.
