[c-nsp] High load problem on 7206 vxr

[Rodney Dunn]

One thing I can say is that 12.1E will not have any
of the recent performance enhancements for scalability
for broadband aggregation.

That code is closed for any new enhancements and is bugfix
only now.

You should consider 12.3 or 12.3T for broadband aggregation.
