[cisco-nas] L2TP - va bandwidth

[Dennis Peng]

I think it's time we started a mailing list for discussion of
BroadBand Aggregation (BBA) questions and issues. I'll contact the
host of cisco-nas to see if they could host this.

The bandwidth is set by the value of the Tx and Rx Connect Speed AVP
in the ICCN that is sent by the LAC. If you do "debug vpdn
l2x-packet", you should see the decodes of the AVP that the LAC sends.

If the LAC sends the correct speed information to us, then the
interface will reflect that information.
