@karuturi we use [Ansible](http://docs.ansible.com/) 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.
