Bug 251725

Description of problem: Once started, the nVidia CK804 ethernet driver wakes up
100 times per second, regardless of process use.  It even continues waking up
100/sec when the ethernet is idle (no packets on wire) or when the cable is
disconnected.


Version-Release number of selected component (if applicable):
kernel-2.6.23-0.74.rc2.git1.fc8

How reproducible:
always

Steps to Reproduce:
1. boot to single-user mode, run "powertop -d", note absence of ethernet wakeups.
2. "telinit 3" to multi-user mode; run "powertop -d"; ethernet is 100/sec.
3.  kill all processes that were added by going multi-user; run "powertop -d";
ethernet is still 100/sec.
  
Actual results:  ethernet wakes 100/second


Expected results: no ethernet wakeups if not being used by process and no
packets on wire (silent network, or unplugged wire.)
