[c-nsp] TFTP/SCP

[Alex Pressé]

I've dumped images in a place available via HTTP.

The nice thing about SCP is being able to push the image directly to the
switches instead of having the switches pull. When pushing the image, SCP
also offers the ability to limit bandwidth (thus preventing your CPU spike).
