+	/*  The fan failure mechanism is usually related to the PHY type
+	  since the power consumption of the board is determined by the PHY.
+	  Currently, fan is required for most designs with SFX7101, BCM8727
+	  and BCM8481. If a fan is not required for a board which uses one
+	  of those PHYs, this field should be set to "Disabled". If a fan is
+	  required for a different PHY type, this option should be set to
+	  "Enabled".
+	  The fan failure indication is expected on
