Return the current fqdn of the machine, trying hard to return a meaningful

In particular, it means working against a NetworkManager bug which seems to
make C{getfqdn} return localhost6.localdomain6 for machine without a domain
since Maverick.

Return the ethernet device's advertised link speed.
The return value can be one of:
* 10, 100, 1000, 2500, 10000: The interface speed in Mbps
* -1: The interface does not support querying for max speed, such as
virtio devices for instance.
* 0: The cable is not connected to the interface. We cannot measure
interface speed, but could if it was plugged in.
