[c-nsp] Real quick interface statistics question

[Rodney Dunn]

If you overrun the fifo buffer before the packet can pulled off the rx ring
if it's a software forwarding platform. Not sure exactly when it would
be incremented for a hardware forwarding platform. A lot of times those
counters are overloaded with different reasons.

That number is so low compared to the overall rate it's usually attributed
to microburst.
