CVS commit: syssrc/sys/dev/pci

[Manuel BOUYER <bouyer%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   bouyer

Modified Files:
        syssrc/sys/dev/pci: if_ste.c

Log Message:
Rework transmit underrun logic:
- when a transmit underrun occurs, only reset the transmit logic. This prevents
  the link from going down at the MII level (the same logic can probably
  be used for other transmit errors)
- set the urgent threshold to half the start threshold. From experiments
  this helps a bit decreasing the number of underruns

Now that underruns don't cause the interface to stop for several seconds,
make back out the default transmit threshold to 128.
