High performance patch for openssh

Issue

• SCP and the underlying SSH2 protocol implementation in OpenSSH is network performance limited by statically defined internal flow control buffers. These buffers often end up acting as a bottleneck for network throughput of SCP, especially on long and high bandwith network links. Modifying the ssh code to allow the buffers to be defined at run time eliminates this bottleneck. We have created a patch that will remove the bottlenecks in OpenSSH and is fully interoperable with other servers and clients. In addition HPN clients will be able to download faster from non HPN servers, and HPN servers will be able to receive uploads faster from non HPN clients."
• Please incorporate this patches to openssh in rhel5 and rhel6
• This patch is a nice to have, and simply improves scp performance. This patch will dramatically improve throughput, many examples are displayed at http://www.psc.edu/networking/projects/hpn-ssh/
• Does OpenSSH support HPN-SSH in Red Hat Enterprise Linux 5?
