Dell generally used Broadcom Ethernet chips, but the support is good for
those as well.

I haven't had problems with the mpt-based machine I have, but reportedly
the driver doesn't handle certain error conditions.  I believe a new

I had problems with an IBM machine a while back and IM just Not Working,
but I haven't tried it recently.
