[c-nsp] EoMPLS on 7401ASR

[Ge Moua]

arie, thank you for the explanation.

I have seen the PXF engine on the 7304/nse-100 cause out-of-order packet 
for L2 protocols like VTP (and disabling PXF did remedied this), however 
I was told that by TAC this was a bad idea.  What we ended doing was use 
VTP transparent mode (so VTP updates are not neeed) and enabling PXF.

Thanks again.
