You are running this on ingress. If you run on egress you will see
proper header.
_Most people_ want to see the whole original header for qos accounting
purposes etc. PPPOE claims to be ethernet, PPP does not. Hence
difference in observation. 

We could add an override feature to say "i only want 
see what was passed not wire packet". 
If this is important to you let me know and i will try to make time to
add it (with hopefully not breaking old scripts); if you feel brave as
well i could guide you on how to add it.

cheers,
jamal
