Created attachment 337952 [details, diff] Patch to correct version of HPN patches. OpenSSH add HPN (High Performance SSH/SCP) patches. Following https://www.psc.edu/index.php/hpn-ssh, there is a specific version of the patches for a specific version of OpenSSH, the current .ebuilds don't follow this. So I propose a patch to correct this.
