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.
