Some more information for those looking to reproduce this: the above is
with rxcsum and txcsum disabled in the xn interface: Without that, the
ssh client on the other side would just say 'Disconnected: Packet corrupt'.

With tx/rxsum disabled, the ssh client will seem to hang, while the
server spits the xn_txeof message.


I seem to recall that disabling TSO helped fix a similar error under
Citrix XenServer, but alas. No difference.
