From 84314bf92265bccea601ed75ec93944e1a36dd81 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 8 Jan 2009 11:01:58 -0800 Subject: r6040: check PHY status when bringing interface up This patch makes the driver properly initialize the PHY status if not correctly set by the bootloader/BIOS. It prevents some boards to bring up the link on boot. Signed-off-by: Florian Fainelli Signed-off-by: David S.
