+ * - Name
+ - Type
+ - Mode
+ - Description
+ * - ``flow_steering_mode``
+ - string
+ - runtime
+ - Controls the flow steering mode of the driver
+
+ * ``dmfs`` Device managed flow steering. In DMFS mode, the HW
+ steering entities are created and managed through firmware.
+ * ``smfs`` Software managed flow steering. In SMFS mode, the HW
+ steering entities are created and manage through the driver without
+ firmware intervention.
+ * - ``fdb_large_groups``
+ - u32
+ - driverinit
+ - Control the number of large groups (size > 1) in the FDB table.
+
+ * The default value is 15, and the range is between 1 and 1024.
+
+The ``mlx5`` driver supports reloading via ``DEVLINK_CMD_RELOAD``
