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> --- All drivers that update the link status are supposed to set it down initially. These drivers will need to be tested to verify that if the physical link is already up then they update the link status correctly when the interface is brought up.
