From d00614c0570656480d6dea5c84c1caec58f40021 Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Thu, 20 Sep 2018 21:39:31 +0300 Subject: IB/mlx5: Set uid as part of XRCD commands Set uid as part of XRCD commands so that the firmware can manage the XRCD object in a secured way. That will enable using an XRCD that was created by verbs application to be used by the DEVX flow in case the uid is equal.
