I guess I'm still missing something, because you have just as much chance
to catch the logical state in DOWN as seeing the physical state in Polling
(if the logical state is INIT then the phys state will always be LinkUp).

In any case I added a phys_state attribute in sysfs because I guess it
can't hurt.
