uclinux and thriple speed ethernet

Hello.

Im trying to get ethernet working on my cyclone3 dev board with uClinux. Im using the sof from the udp offload example at nioswiki.com(http://www.nioswiki.com/exampledesigns/nios2udpoffloadexample) and my own kernel. It boots fine:

From this, it seems that the device drivers works.

I run ifconfig eth0 <addr> and get:

eth0 up, link speed 100, full duplex, eth hw addr 00:07:ed:0d:09:19

--- Quote End ---

Still seems ok, right?

I have my computer connected to the same switch as the board, and in the same ip range. Now, when i try to ping my computer I get no response but the RX and TX leds on the board lights up. Same thing when I ping the board from the computer; no response but RX-led on board lights up. I also have a dhcp-server running on the computer, but the board cant connect. Apparently, it's incoming traffic to the board that's the problem.

Is it possible that I've configured the kernel wrong? Is there a working kernel.config with ethernet available for this board somewhere?
