I believe this section should be managed by hostapd code (src/contrib/wpa/src/eap_server/eap_server_tls.c) ? But I didn't reach to display the wpa_printf(MSG_DEBUG,...) with hostapd in debug mode. Frame detail in text mode received by freebsd/hostapd (EAP-TLS "more fragment" set), but no ACK (EAP-TLS empty) from freebsd/hostapd.
