[c-nsp] Large-scale site-to-site IPSEC VPN device

[Rodney Dunn]

This was passed over to me on the 3945e:

The 3945e should be able to do this as well.  It has a max limit of 3500
tunnels.... It will also do 330
Mbps encrypted through 2000 tunnels.

Disclaimer: I have not seen the actual testing results for this but to 
pass it as some general guidance.
