Plan 9's ip/ppp doesn't work with my PPPoE ISP (Sympatico).

A few years ago I investigated and figured out how to make
it work.  I think it had something to do with Plan 9's end
of the connection not preserving configuration information
when sending acknowledgements; sorry I can't remember in
more detail.

In case anyone else is having the same problem, here's the
diff.
