      Description

      The following YAML causes a crash

       net:
        - net type: tcp
          local NI(s):
            - interfaces:
                0: eth0
              tunables:
                peer_credits: 32
            - interfaces:
                0: eth1
              tunables:
                peer_credits: 32
            - interfaces:
                0: eth2
              tunables:
                peer_credits: 32
      

      peer_credits and peer_tx_credits default to 0, which causes an NI to be removed prematurely.

      Missing parameters should be defaulted.
