Subject: [net-next 10/15] net/mlx5: Document support for RoCE HCA disablement capability
Date: Sat, 4 Feb 2023 02:08:49 -0800 [thread overview]
Message-ID: <20230204100854.388126-11-saeed@kernel.org> (raw)
In-Reply-To: <20230204100854.388126-1-saeed@kernel.org>
From: Rahul Rameshbabu <rrameshbabu@nvidia.com>
Some mlx5 devices are capable of disabling RoCE. In this situation,
disablement does not need to be handled at the driver level.

enable_roce: RoCE enablement state
----------------------------------
-RoCE enablement state controls driver support for RoCE traffic.
-When RoCE is disabled, there is no gid table, only raw ethernet QPs are supported and traffic on the well-known UDP RoCE port is handled as raw ethernet traffic.
+If the device supports RoCE disablement, RoCE enablement state controls device
+support for RoCE capability. Otherwise, the control occurs in the driver stack.
+When RoCE is disabled at the driver level, only raw ethernet QPs are supported.
-To change RoCE enablement state, a user must change the driverinit cmode value and run devlink reload.
