Okay, but what makes you say that? What did you read that told you
this?
As far as packet sizes, very few DSL connections will have an MTU
even approaching ethernet, so there's already a lot of internal
fragmentation and reassembly going on. PPPoE actually does a pretty
good job of this, despite how much folks around here like to badmouth
it. (Sure, it's hard to set up. But it's doing a hard job.)
