That is expected behavior and can be ignored. hostapd still believes it
is controlling a wireless interface, but the driver_test.c interface
does not really use any device.

Are you running hlr_auc_gw to provide the authentication triplers for

If you are planning on using real USIM cards, you cannot test EAP-AKA
without matching AuC/HLR implementation. hostapd (the hlr_auc_gw part of
it) implements AuC/HLR for generating AKA authentication data using
Milenage algorithm. That can be used with USIM cards that have been
configured to use Milenage with a known private key.
