CVS commit: src/sys/dev/pci

Module Name:    src

Modified Files:
        src/sys/dev/pci: if_bge.c if_bgereg.h

Log Message:
Add hooks to dynamically change the bge Rx interrupt thresholds.  I
found empiricaly that (at least on bcm5700s) the Rx coalesce and bd
counts cannot be updated on-the-fly; attempting to do so (even at
splhigh()) causes weird behaviour.

Instead, add a softc flag to record that the desired softc values for
Rx-interrupt thresholds have changed; check that boolean in the interrupt
routine. If set, apply the new values there and clear the flag.
