AS3.0 - bcm5700 vs tg3 drivers

[Waldher, Travis R]

I've been trying to build a bcm5700 driver for AS3.0.  I get an error
that, in the past, meant the driver wasn't meant for running with my
particular kernel, even if it runs on the 2.4x kernel.

I can't find a bcm5700 driver anywhere so far (started on
www.broadcom.com and fanned out to their OEM distributers), I only find
the tg3.

Is the tg3 driver better in AS3.0?  I know in the Redhat 8.0 days, from
which AS 3.0 was based, the bcm5700 was the preferred driver due to less
bugs, better reliability, etc.
