It seems likely that I got confused by looking tshark, seeing box sending
bigger packets than MTU, but that was likely due to XEN NIC offering
large-segment-offload.
So this may be expected behaviour with no obvious workaround, other than
not using ControlMaster when doing both interactive and sftp/scp to same
host.
