[c-nsp] Gigabit Interface Input Errors

[Drew Weaver]

The card in total when I last added everything all up is doing about 1.9Gbps and 1.4Mpps

What's the utilization on the other 2 interfaces? I am not familiar with
this specific platform, but it might also be caused by slot/backplane
limitations causing packets to be dropped if the total BW exceeds a certain
(non line-rate) value. I have seen this behaviour on some platforms.
