    Use '-p ip' instead of '-p 0' with conntrack
    
    The conntrack command does not allow '-p 0' as an argument,
    but does allow it's equivalent '-p ip'.  Use it instead
    so it doesn't generate an error.

Title:
  conntrack v1.4.4 (conntrack-tools): `0' unsupported protocol

Status in neutron:
  Fix Released

Bug description:
  Hi,

  In neutron-openvswitch-agent.log I got some error related to
  conntrack. I'm not sure about when _delete_conntrack_state function is
  triggered.

  From the code it seem to be related to a port update.

  Does it has something to do with the fact than during security group
  rule creation sometime we could set a number[1] ?
