search for: subsystemrcvbuf

...ystem name would be scp, sftp-server, etc. The command line options would be -r <n> or --rcvbuf <n> to allow one to specify the number passed to SO_RCVBUF. This would allow one to easily add other options (like SO_SNDBUF support). An alternative would be to add the following option: SubsystemRcvbuf <subsystem-name> <n> This would be much easier to implement, but doesn't allow for more options to be added without another keyword. I guess this is the way I'm leaning, but I can be swayed.
