But userppp and pppoe are very different things.  The kernel equivalent
of userppp is ppp(4) and the userland equivalent of pppoe(4) is
rp-pppoe.  The fact that your current setup works (with its drawbacks,
but still) means that you're actually doing PPPoEoA (that is, with an
added Ethernet layer).  If userppp can work with your DSL installation,
you'd better try using ppp(4) if you want the native implementation,
because involving Ethernet in this only brings trouble, notably with
tht MTU.
