[c-nsp] Cisco trunk port startup delay

> @alan - carrier-delay msec 0 did not seem to make any difference, I still
lost 5 pings. I simply turned it on the single interface I am testing with
and assumed it will kick in.

Doesn't the carrier-delay msec 0 affect only the down events if "up|down"
knob is supported by any chance? 
Have you tried carrier-delay up 0 ? 
Also for 0 seconds I'd try it without the "msec" knob.
