As a next step I attempted to load a file via tftp.  This works fine
if the file is <= 544 bytes in length:

Overo # tftp test.txt
smc911x: initializing
smc911x: detected LAN9221 controller
smc911x: phy initialized
smc911x: MAC aa:bb:cc:dd:ee:ff
TFTP from server 192.168.0.210; our IP address is 192.168.0.223
Filename 'test.txt'.
Load address: 0x82000000
Loading: #
done
Bytes transferred = 544 (220 hex)

Files longer that 544 bytes result in a timeout error:

Overo # tftp test.txt
smc911x: initializing
smc911x: detected LAN9221 controller
smc911x: phy initialized
smc911x: MAC aa:bb:cc:dd:ee:ff
TFTP from server 192.168.0.210; our IP address is 192.168.0.223
Filename 'test.txt'.
Load address: 0x82000000
Loading: T T T T T T T T T T
Retry count exceeded; starting again

Any ideas what might be going wrong here?
