Hello,
I guess you are using 10MB ethernet. In the 440 is between EMAC and PHY
inserted so called ZMII bridge, which can operate in several modes. If
is in the RMII mode then is necessary to set correct speed in the ZMII
Speed Select Register.
The following patch will fix this problem.

There are three ways to get something done: do it yourself, hire
someone, or forbid your kids to do it.
