Doing simple iperf test on new opteron with tg3 against existing Xeon
system.  I am seeing something wierd, the connection hangs right away.
Is this a TSO bug.  

Sender: BK latest (2.6.9-rc3) Tg3 (XX.YY.250.3)
Receiver: BK + netdev(jeffm) + dave's latest e100 (XX.YY.1.73)

Both machines are directly connected with a netgear 100mbit switch.
