selftests/net/fcnal-test.sh: ipv6_bind failed

[Zhou, Jie2X]

hi,

   I test ipv6_bind by "fcnal-test.sh -v -t ipv6_bind" in kernel v5.16-rc3.
   There are two tests failed.

TEST: TCP socket bind to out of scope local address - ns-A loopback IPv6      [FAIL]
TEST: TCP socket bind to VRF address with device bind - VRF IPv6              [FAIL]

 In fcnal-test.sh expected command error not occurred.
 ipv6_addr_bind_novrf()
  {
......
        log_test_addr ${a} $? 1 "TCP socket bind to out of scope local address"

 ipv6_addr_bind_vrf()
  {
......
        log_test_addr ${a} $? 1 "TCP socket bind to VRF address with device bind"

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

best regards,./fcnal-test.sh -v -t ipv6_bind
