Subject: [PATCH v2] smsc95xx: mark link down on startup and let PHY interrupt deal with carrier changes

Without this patch sysfs reports the cable as present

flag@...g-desktop:~$ cat /sys/class/net/eth0/carrier
1

while it's not:

flag@...g-desktop:~$ sudo mii-tool eth0
eth0: no link

Tested on my Beagle XM.

v2: added mantainer to the list of recipient
