[c-nsp] Problems bringing up BGP session

[james edwards]

I moved the BGP session to a new router for my Quagga route server. It was
working before the move but now it comes up,
the RS gets all the routes and in ~5 mins. the session goes down. This looks
like bug  CSCsv33977. I can't apply the workaround
as I do not have the command "dont-capability-negotiate":
