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

ping failed; host 10.0.0.26 is not alive

MII info and dump result in the following output:

netmask=255.255.255.0
hostname=EP82xxM
ethprime=FCC3 ETHERNET

Thanks for your help!
