[c-nsp] CBWFQ, 2821, dialer interfaces and 12.4

[Nigel Camp]

Hi Brett,

This sounds similar to CSCsb02533.

This bug only affects the counters when doing ppp multilink over dsl,  
where the packet matches are seen under the Dialer interface, and the  
queuing is seen under the Virtual access interface that the
MLP binding is on.

Tac said this was a cosmetic issue, because if you combine the output  
of the two you will get the full picture.

On a different angle, whenever we do QoS over DSL, we always place  
the service policy under the ATM pvc, not the Dialer interface.

The counters and queuing always work with this configuration, which  
is not the same experience i've had on Dialer interfaces that aren't  
multilinked.

Cheers,
Nigel
