I don't know why the file isn't being created, but I would expect the ethernet
connection to work anyway. If you want to create the file by hand, something
like
this should work:
echo "SUBSYSTEM==\"net\", ACTION==\"add\", DRIVERS==\"?*\", \
ATTR{address}==\"00:04:xx:xx:xx:xx\", ATTR{dev_id}==\"0x0\", \
ATTR{type}==\"1\", KERNEL==\"eth*\", NAME=\"eth0\"" \

Change 00:04:xx:xx:xx:xx for your actual mac address
