I am currently working u-boot for AT91SAM9260 based board. In this board we are using LXT971A as phy rather than davicom dm9161a as in AT91SAM9260-EK. We have u-boot-1.1.5 version with AT91SAM9260 support, but it is having phy support only for Davicom dm9161a . So we have changed the phy driver by making appropriate modifications in Davicom dm9161 to make suitable for LXT971A . We have downloaded the image in flash. We have connected one ethernet cross cable between the board and one PC.After rebooting we are observing the following

1. Initially auto negotiation is happening with the PC.And tried to ping the

PC from u-boot. 2) While pinging from the u-boot, the request is not coming to the Computer(We checked up with Ethernet sniffers like Ethereal), 3) In u-boot after ping request it will wait for the reply from the other side, it is receiving packets from my Computer (It is not the reply of ping, some other broad cast message). So my conclusion is that, the Ethernet packets from U-boot is not reaching up to the Computer but packets from the Computer is receiving there inside the board.

I don't know any one you face the same problem. So I request you to reply if you have any clues to solve the issue.

check the discussion and patches in this thread:
