Well - it does that for incoming packets *after* the BPF tap, then tries
to find someone interested in them and drops them if it doesn't find
anyone. That's nearly the same behaviour as without PPPoE interfaces, where
the packets are dropped imediately after the BPF tap.

This used to work (i.e. I successfully ran rp-pppoe whith a kernel that had a
pppoe0 interface). I will check if something broke...
