+Description:
+                The maximum PHY rate to use for all connected devices.
+                This is only of limited use for testing and
+                development as the hardware's automatic rate
+                adaptation is better then this simple control.
+
+                Refer to [ECMA-368] section 10.3.1.1 for the value to
+                use.
