[PATCH rdma-next 08/25] IB/mlx5: Set uid as part of CQ creation

From: Leon Romanovsky <leon@kernel.org>
Date: 2018-09-17 16:31:46
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 CQ creation so that the firmware can manage the
CQ object in a secured way.

The uid for the destroy and the modify commands is set by mlx5_core.

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