Hi Jouni, It is because the value is not conceptually available where auth takes place before assoc. https://tools.ietf.org/html/rfc3580#section-3.4 "Where IEEE 802.1X authentication occurs prior to association, a unique NAS-Port value may not be available." hostapd always sends a value of 0 in this scenario.
