[c-nsp] Strange ME3400 PPS Limit

[Jeremy Parr]

I have an ME3400 running 12.2(46)SE that will not pass (much) more
than 1000pps through its copper gig port. The interface counters hover
around 1000pps tx/rx, while the bps rate fluctuates (presumable due to
the variable packet sizes getting thrown at it). There are no service
policys or rate limits applied to any of the interfaces. Any thoughts?

  5 minute input rate 1681000 bits/sec, 879 packets/sec
  5 minute output rate 7545000 bits/sec, 1012 packets/sec
