[c-nsp] 7200 NPE-G1 and 802.3x

[Kevin Graham]

Has anyone ever seen the onboard gigabit's of an
NPE-G1 actually attempt flow control?

Sample 2821 looks great, a few overruns, but with
pause frames to match:

2821#sh int gig 0/0 | inc over|pause|low
  output flow-control is XON, input flow-control is
XON
     550 input errors, 0 CRC, 0 frame, 17 overrun, 533
ignored
     0 watchdog, 0 multicast, 0 pause input
     0 lost carrier, 0 no carrier, 823 pause output
2821#

...however every NPE-G1 (not pushing any G2's hard
enough yet to rack up overruns) I've looked doesn't
appear to make an attempt:

npeg1#sh int gig 0/2 | inc over|pause|low
  output flow-control is XON, input flow-control is
XON
     179528 input errors, 0 CRC, 0 frame, 179528
overrun, 0 ignored
     0 watchdog, 3794836 multicast, 0 pause input
     1 lost carrier, 0 no carrier, 0 pause output
npeg1#

Am I missing something obvious?
