selftests/net/fcnal-test.sh: ipv6_ping test failed

hi,

  I test ipv6_ping by "./fcnal-test.sh -v -t ipv6_ping".
  There are two tests failed.

   TEST: ping out, VRF bind - ns-B IPv6 LLA                                      [FAIL]
   TEST: ping out, VRF bind - multicast IP                                       [FAIL]

   While in fcnal-test.sh the expected command result is 2, the result is 1, so the test failed.
   ipv6_ping_vrf()
   {
    ......
        for a in ${NSB_LINKIP6}%${VRF} ${MCAST}%${VRF}
        do
                log_start
                show_hint "Fails since VRF device does not support linklocal or multicast"
                run_cmd ${ping6} -c1 -w1 ${a}
                log_test_addr ${a} $? 2 "ping out, VRF bind"
        done

    The ipv6_ping test output is attached.
    Did I set something wrong result that these tests failed?

best regards,
