On one of my arm box, I can reproduce the problem with below
command every time:
$iperf -c $SRV -l 2398 -n 1 #the 2nd tcp packet
length is 1016
and the oops is same with Thomas's. After applying Oliver's patch,
I still can see zlp padding packet is appended, but no oops any more.
Thanks Oliver for fixing the problem.
Thanks,
