Why do you care? I'm having trouble thinking of a reason to care, and, actually, I'm not sure you _should_ be able to tell. Indeed, the concept we usually think of as a network interface is a virtualization, provided (by the driver and some pieces of MI kernel) atop the actual hardware. Also, I could argue whether ppp is virtual or not; it seems to me it's a defensible position that ppp, at least when connected to a real serial port, is as real an interface as any Ethernet, just using (very) different layers 1 and 2. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
