+Subject: [PATCH] net: genet: enable link energy detect powerdown for
+ external PHYs
+
+There are several warts surrounding bcmgenet_mii_probe() as this
+function is called from ndo_open, but it's calling registration-type
+functions. The probe should be called at probe time and refactored
+such that the PHY device data can be extracted to limit the scope
+of this flag to Broadcom PHYs.
+
+For now, pass this flag in as it puts our attached PHY into a low-power
+state when disconnected.
