TEST PROCEDURE

 The following tests are prepared in this test package. See INDEX file.

Test for a Host and Router

   DAD Fail when NUT received Valid NS (dst MAC addr != MAC addr of NUT) on Stateless Link-local address autoconfiguration
   DAD Fail when NUT received Valid NA (dst MAC addr != MAC addr of NUT) on Stateless Link-local address autoconfiguration
   DAD Fail when NUT received Valid NS (dst MAC addr == MAC addr of NUT) on Stateless Link-local address autoconfiguration
   DAD Fail when NUT received Valid NA (dst MAC addr == MAC addr of NUT) on Stateless Link-local address autoconfiguration
   DAD Fail when NUT received NA (No TLL option) on Stateless Link-local address autoconfiguration
   DAD Fail when NUT received NA (dst addr == solicited node multicast) on Stateless Link-local address autoconfiguration
   DAD Fail when NUT received Valid NS (dst MAC addr == MAC addr of NUT) on Manual Global address configuration
   DAD Fail when NUT received Valid NA (dst MAC addr == MAC addr of NUT) on Manual Global address configuration

Test sequence

  TN(or X)                   NUT
  ------------------------------
  Initialize NUT (see ...)

  Configure address of NUT (boot or manual or ra, see ...)

  TN wait the DAD NS sends from NUT
  <=== Judgement #1: DAD NS ====
        name: dadns_from_NUT

  Immediately (within $RetransTimerSec [sec]) send DAD Packet to force NUT to detect address duplication.
  ==== Action #1: DAD NS ====>
        name: dadpkt_to_NUT

  Wait for NUT to finish DAD. (sleep $RetransTimerSec [sec])

  Check if NUT's address is not configured
  ==== Action #2: DAD NS ====>
        name: chkconf_dadns_to_NUT

  DAD NA does not come because NUT detect address duplicated and address is not configured.
  <=== Judgement #2: DAD NA does not come====
        name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)
