usbnet: Set link down initially for drivers that update link state
Some usbnet drivers update link state while others do not due to hardware limitations. Add a flag to distinguish those that do, and set the link down initially for their devices. This is intended to fix this bug: http://bugs.debian.org/444043 Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
