[c-nsp] IPv6 subnets for point-to-point links

[Yucel Guven]

Crist,
Routers need to identify networks uniquely, e.g, if a router has 50 x p2p
subinterfaces, it must know into which subif the packet has to be forwarded.
For this purpose, netmasks are inevitable.
IPv6 doesn't need any broadcast mechanism, but we still need to identify 
our subnets, uniquely.
Btw, I also used /126 for p2p links on GSR12000 (with T-series image) without any problem
