[c-nsp] MPLS capabilities of SUP2

[Oliver Boehmer (oboehmer)]

As many others will suggest: The PFC2 on the Sup2 has *no* MPLS
capability, it can't switch MPLS-tagged packets. Period :-|

So unless you're using your Sup2 as pure Layer 2 (then it doesn't care),
you need to buy OSMs or Flexwans to do the tagging, so you want to go
with Sup720 or Sup32..
