+          The RapidIO specification describes a Output port transmit
+          enable and a Input port receive enable. The recommended state
+          for Input ports and Output ports should be disabled. When
+          this switch is set the RapidIO subsystem will enable all
+          ports for Input/Output direction to allow other traffic
+          than Maintenance transfers.
