Because of numerous reported problems with the tg3 driver, mainly
on amd64 (x86_64/Opteron/Athlon64) boxes, we made a kernel patch
from the latest official BCM5700 2.4 driver for the 2.6 kernel.
This seems to resolve those problems, though also seems to be
a much larger driver than the tg3 driver.

Please CC me on any replies as I am not subscribed to this list.
I also figured it would be ok to submit, as there's the eepro100 and
e100 drivers for the intel nic, figured this was a similar instance.
