[f-nsp] mpls + bgp support on NI CES2K

[David Unfried]

Based on my first hand observation using a CER, the CER is FPGA based

FWIW, I'm pretty sure neither the CES or CER are merchant silicon. In fact,
I'm pretty sure the forwarding plane on these guys are FPGA based.

That being said, the CES does have less CAM than the CER does, sip that does
limit scalability.  Otherwise the difference is in the licensing model in
the control plane.

I'll also say, my message to vendors is consistently that software feature
licenses are a negative mark when I'm considering gear. If Brocade/Foundry
people are listening, please take this message back to your product
management people.
