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.
