bpo-31904: skip test_getaddrinfo_ipv6_scopeid_symbolic and test_getnameinfo_ipv6_scopeid_symbolic on VxWorks by pxinwr · Pull Request #23518 · python/cpython
The API if_nameindex() is not available in VxWorks' user space in which Python runs. The script configure will undefine HAVE_IF_NAMEINDEX so that socket module has no attribute if_nameindex. Skip the tests impacted by this.
