Hi, I had similar problem on my development board. Check storing address - I had bad store link address. And dumping ethernet packets with tcpdump or ethereal. Print it and check it with md command and compare with dumping packets.

I am having trouble getting Ethernet to work correctly on our Embedded Planet EP82xxM board. Specifically, pings and TFTP transfers fail when the board is populated with an MPC8250 or an MPC8270. However, when the board is populated with an MPC8280 processor, Ethernet works. Any suggestions of things to try out to resolve this would be greatly appreciated.
FCC2/3 port pins appear to be correctly configured. PHY registers are able to be accessed and seem to show the correct configuration. No packets are appearing on the wire when sniffed with Ethereal. With ET_DEBUG turned on, pinging results in the following output:
ep82xxm=> ping 10.0.0.26 Using FCC3 ETHERNET device sending ARP for 0a00001a ARP broadcast 1 packet received packet received Receive from protocol 0x0 packet received packet received Receive from protocol 0x0 . . . ARP broadcast 2 packet received packet received Receive from protocol 0x0 packet received packet received Receive from protocol 0x0 . . . ping failed; host 10.0.0.26 is not alive
MII info and dump result in the following output: ep82xxm=> mii info PHY 0x00: OUI = 0x04DE, Model = 0x0E, Rev = 0x02, 100baseT, FDX PHY 0x01: OUI = 0x04DE, Model = 0x0E, Rev = 0x02, 10baseT, HDX
