[c-nsp] Compression on MPLS

hello,

 just a theoretical Q:

 couldn't compression be done in CEF process-path?
CEF: so the labels could be determined from the CEF table
process path: still punted, so that the CPU can do it's compression task?

  on 12.2M being old: it's the youngest GD code ;)

unless something chanaged quite recently (but you're running 12.2M, so
rather old code), stac compression will punt the packet to the process
path, which usually breaks cef/mpls-vpn.
