[c-nsp] Use "plain old IP" for non-VRF traffic?

[Phil Mayers]

We have an MPLS L3VPN-based network, and I want to use plain-old IPv4 
(no labels) for the non-VRF traffic.

The reason I want to do this is we're seeing a bug related to 
VACL-capture - packets whose next-hop is a label-imposition are not 
captured. I'm going to deal with that separately via TAC, but we need 
the VACL capture to work ASAP.
