Bug#861078: /usr/bin/ssh: Unsupported option "compressionlevel"

[Philipp Marek <philipp.marek@linbit.com>]

Package: openssh-client
Version: 1:7.5p1-2
Severity: minor
File: /usr/bin/ssh

When starting SSH connections, I get a warning:

    ~/.ssh/config line 152: Unsupported option "compressionlevel"

But the man page "ssh_config" clearly states this option,
and I can't find anything in the changelog that this option was removed.


    # grep compression ~/.ssh/config -i
    Compression yes
        CompressionLevel 9

The latter one is in a "Host" match block.
