The SMP bug isn't in the drivers, it's in the SMP interrupt dispatch. The
best the driver can do is detect that it's occuring.

The tulip.c driver has been updated every two weeks or so for the past year
to support various new boards and chips. The one distributed with the
kernel is rather old, but I think this report was using a more recent
version.
