We use the bcm5700 driver with our distribution.  Although we have to
frequently update it to support new IDs, it has been much more reliable
than the tg3 driver.

The tg3 driver has had many new versions that claim to have fixed all of
the serious problems with the previous version, and be even faster.  But
some of the new versions are closely tied to subtle interface changes in
2.5, which makes it risky to just back-port to production kernels
without careful study of what the changes mean.

[[ Of course, I have strong personal opinions about network driver API
changes, backward compatible stable driver releases and the difficulty
of keeping driver code working.  I'm not above saying "not as easy as it
looks from the outside, eh?". ]]
