Given a 10 Mbit/s ethernet device (eth0) which is used to establish a
PPP over ethernet (PPPoE) connection (ppp0) to a broadband ISP (e.g. 
using ADSL, SDSL and so on as an underlaying system). 

If I then want to shape the traffic I send to the "ppp0" interface,
which bandwidth would be used for setting up a CBQ? 

I suppose that here the "virtual" (e.g. limited by the ISP) bandwidth 
of my "ppp0" connection (e.g. 128 kbit/s) is the interesting one, not 
the bandwidth of my "eth0" (10 Mbit/s), because the CBQ is attached
to the "ppp0" device and has nothing to do with the underlaying "eth0".

Is this assumption correct?

TIA,
Steffen
