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
