I use the D-Link DFE570TX card in several routers here. And I don't use
the regular tulipdriver, it has problems with high packetrates yes, mostly
because of high irqloads. I use the NAPI enabled tulipdriver and I have no
problem routing 64byte packets at wirespeed here (148.800pps).

I think the same NAPI tulipdriver works with this card aswell.

You can find the NAPI patch and tulip NAPI driver here:

ftp://robur.slu.se/pub/Linux/net-development/NAPI/

They are currently working on optimizing the intel e1000 driver.

Never argue with an idiot. They drag you down to their level, then beat you with experience.
