  Um.  DSL isn't Ethernet.  It actually closely resembles a high-speed
serial connection.  PPP makes sense.  If your DSL equipment is giving
you an IP-over-Ethernet, it's because the "modem" is doing some kind
of frame encapsulation (probably using something that smells like
ATM), or because it's terminating a PPP connection internally.  But
it's always doing *something*.  You can't just hook an Ethernet cable
up to a phone line.
