[c-nsp] ISIS / NSF IOS XR

[Atif Sid]

yes correct ! NSF is disabled

but if you look closely 'sh isis neig' command says capabale 'yes' ; but
ISIS adj command say NSF 'yes' which is misleading !

I have LDP GR also disabled. but when I failover RP's i do not see any
traffic loss.

have you tested !
