[rbak-nsp] SMS PPPoE RADIUS Config

[Scott Helms]

Chris,

     Is there a reason you need to control the PVC via RADIUS?  The 
actual data that has to be passed back to the SMS from the RADIUS server 
is really very basic and I'd get that working first and then if you need 
to control the PVCs that way add it in later.  In short, pull all of the 
PVC references out and any Redback VSAs you have returning since you 
don't need them for basic authentication.
