This is a fix for the poor performance for when OpenSSH clients are sending to HPN-SSH installs. The cause of this problem is still under investigation but is related, in some way, to the channel input buffer hitting a limit of 16MB. This value corresponds to the advertised application layer receive window sent by the HPN install. The fix is to limit the advertised window to 15MB. This does impact performance - which is annoying. More work will hopefully uncover a better long term fix.
