[c-nsp] 6500/BGP/full route tables [even more] confusing...

[Tim Stevenson]

DFC is optional on CEF256 cards. CEF256 is just a family name. The 
"dCEF" under CEF mode indicates whether it's doing central or 
distributed (d = distributed, ie, DFC).

sh module will clearly tell you whether a DFC is present or not, 
under the Sub-Module heading.
