Re: [libvirt] [PATCH] virNetDevGetLinkInfo: Don't report link speed if NIC's down

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.
