Dynamic WEP keys require that you use an EAP method capable of
generating master keys. Minimal authentication server in hostapd is not
able to do this and it cannot thus be used for such a test. You will
need to setup external RADIUS server and use, e.g., EAP-TLS, EAP-PEAP,
or EAP-TTLS for this to work.
