	src/sys/dev/pci: if_vr.c if_vrreg.h

Log Message:
Pull several fixes which improve TX error handling
from FreeBSD's if_vr.c rev 1.52:
- check more error status in TX descriptor and restart TX module
  appropriately in vr_txeof()
- check more error interrupt status in vr_intr()

I can't confirm whether these changes actually fix TX stalls because
I can't reproduce the problem I had about seven years ago (I guess
it might be caused by excessive collisions on a dumb hub), but at least
they don't seem to have bad side effects on normal operations on my macppc.
