I've never liked the tg3 module...it's always had issues with speed
negotiation and the like.  One way around is to turn off negotiation on
the switch/router and set it to fixed (along with the other appropriate
parameters) and do the same for the machine itself.

If you're using the tg3 driver for a Broadcom chipset, try to use the
actual Broadcom driver (from their website).  It doesn't have these
issues.
