It's not a 802.11 fragment frame, but 802.1x/EAP-TLS fragment frame.
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.
