So I guess Someone should report a bug upstream; it seems obvious that
the upstream patch should adjust the example config files and
ssh_config/sshd_config to explain the new options.  But perhaps they do
and we didn't apply that part.

Thanks - that looks interesting but a little adventurous, and currently
not our big issue.

Hving read their page, I have no idea why performance would be lower and
particularly all the way down to 20 MB/s.

There is also talk of adding a NONE cipher back, and I hope we didn't do
that (but it seems highly highly unlikely we would have).
