The kernel's more broken than one would think. Various drivers report various (usually spurious) values if the interface is down. While on some we experience -EINVAL when read()-ing the speed sysfs file, with other drivers we might get anything from 0 to UINT_MAX. If that's the case it's better to not report link speed. Well, the interface is down anyway.
Wow, that's really awful. I think that warrants a bug report against the kernelt too since such inconsistency can't be useful to anyone.
