[c-nsp] mapping VPDN callers to a particular tunnel...

[Robert E. Seastrom]

So, I'm trying to track down a performance issue, and I'm hoping that
there is a way to map either a user (caller) or a virtual interface to
a particular L2TP tunnel.

IOS is Version 12.3(14)T6, platform is 7206VXR.  Running as an LNS (PPPoVPDN).

Thanks in advance for any clues...
