Currently the appropriate input YAML should look like:

net:
    - net: tcp3
      status: up
      interfaces:
         0: eth4
      tunables:
          peer_timeout: 180
          peer_credits: 8
          peer_buffer_credits: 0
          credits: 256

The problem is that the input and output YAML format is different. We should make them consistent, so that output can be fed as input.
