From d63ea0cc6bfa438fd1a3ef7c336a3418e2b7b22b Mon Sep 17 00:00:00 2001 From: Jonathan Bell Date: Tue, 14 May 2019 17:17:59 +0100 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.
