Hi Alexander,
As requested on bug #320652, here's the lshal output for my tap0 vs.
eth0 devices. The key difference I notice is the
net.originating_device, which shows only
'/org/freedesktop/Hal/devices/computer' for tap0 - I think this
corresponds to the fact that /sys/class/net/tap0/ has no 'device' entry,
and seems to be an accurate way to distinguish physical devices from
virtual ones.
