Some OpenSSH parameters are not compatible with Solaris SSH.
They do break if they are included into the configuration file(s).
This patch does not include them by default on Solaris anymore.
Changed parameters:
sshd_config_tcp_keepalive (TCPKeepAlive in sshd_config)
sshd_config_permittunnel (PermitTunnel in sshd_config)
sshd_config_maxsessions (MaxSessions in sshd_config)
ssh_config_hash_known_hosts (HashKnownHosts in ssh_config)
