Subject: [PATCH 542/782] 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.
