Scope ID support is needed since the kernel's NSM implementation is
about to use these displayed addresses as a mon_name in some cases.
When nsm_use_hostnames is zero, without scope ID support NSM will fail
to handle peers that contact us via a link-local address. Link-local
addresses do not work without an interface ID, which is stored in the
sockaddr's sin6_scope_id field.
