Confirmed location using 4.5 systemvms. LGTM, merging.

@resmo May I know how you discovered this?
AFAIK, scp and sftp are working fine from ssvm and we do not need sftp server on ssvm
Can we remove this subsystem?

@karuturi we use Ansible to manage the routers ad-hoc (config fixes, package updates, security fixes, etc). Ansible uses SFTP for file transfer per default (but it can be configured to use SCP as fallback). So we discovered this issue while debugging.

I can not confirm SFTP works without this patch. This patch fixed the SFTP functionality for us. I see no reason why the SFTP subsystem should be removed.

On the other hand, SFTP has less overhead then SCP (aka faster) and in a big environment of hundreds of routers, this is performance gain.

So voting against removing the subsystem.

@resmo Thanks for the explanation.
+1 for the sftp-server if it makes it faster :)
