Upgrade igor_mac to eth_ocm

Hello NiosII users.

I'm trying upgrade my ethernet core, from igor_mac to eth_ocm (OpenCores 10/100 Ethernet MAV Avalon) module. But i have a lot of problems.

My current configuration, with eth_ocm module.

In eth_ocm conf, all is default.

In uCLinux, I'm using igor_mac driver. It's correct?

When I run the system, has received a message "LINK DOWN", but with the ifconfig, it is present and configured. RX and TX packets are computed, no errors, no dropped. But don't work!

What am I doing wrong?
