Ok. I was trying to make my setup here as close to your code to try and
see the problem. Would you say that the linux-stable tree at 3.4.9 has
the same tg3 code as your distro?
I'm not able to see a problem with 3.4.9 at gigabit or 100mbit on my
setup here.

Asking more about the physical setup to see what is different with the
failing one w.r.t the working case. Is this a gigabit router/switch/hub?

Probably stupid question but have you have tried a different cable?
You mentioned that the switch side works with a laptop? What is the link
speed on the laptop at that time?
