[c-nsp] IOS SLB support

[Frank Bulk]

Asbjorn:

Really, is there something special about the RSP720 that prevents them from
including that feature?  Or is this something I can request from my
salesperson?

I know that CSM and ACE are use in high-traffic situations, but what's the
rule of thumb for moving from IOS SLB to a separate blade?

It is my understanding that there will never be IOS SLB on the
RSP720. Have you been told otherwise? It sure isn't supported
today, re. http://tinyurl.com/2f4mqc.

The CSM works it's magic using network processors on the module,
but it's still configured from IOS, close to the same config as
with IOS SLB. However, the CSMs are not supported in 12.2 SR.

A later release should add RSP720 support for the ACE, which also
works on network processors (though much faster than the CSM),
but is configured from a separate (IOS-like) command line.
