[c-nsp] Mass-renaming interfaces

[cnsp at marenda.net]

I would avoid using gig 0/3 and would not bundle it with gig0/[012] . 

Gig0/0 0/1 0/2 are marvel SOCs build-in Ports 
while Gig0/3 together with the Mangement "Fas"0/0 are on a separate intel
ethernetcontrollerchip 
(with gig+(only)fas they try tonot oversubscribe the internal pci bus )
