From 7bdd305e024d78cfb4f32a1badeb5562791ee5b8 Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Mon, 30 Apr 2012 07:56:50 +0000 Subject: [PATCH] smsc75xx: mark link down on startup and let PHY interrupt deal with carrier changes This patch fixes the same issue as reported on smsc95xx, where the usb device is connected with no ethernet cable plugged-in. Without this patch sysfs reports the cable as present flag@flag-desktop:~$ cat /sys/class/net/eth0/carrier 1 while it's not: flag@flag-desktop:~$ sudo mii-tool eth0 eth0: no link Signed-off-by: Steve Glendinning Signed-off-by: David S.
