- 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.
