That looks quite interesting combination ;-). Nice to hear it worked.

While implementing the eap_example code, some areas started looking
worse than I had hoped for and I think I will end up cleaning the
interface a bit to make it less complex and to require less code in
whatever is using the EAP state machine. Though, this is more on the EAP
peer side, so that part may not touch the particular example you showed
above. I already did some cleanup on the server side some time ago when
updating hostapd EAPOL/EAP state machine interfaces.

In addition, I have a longstanding to-do item on implementing a generic
buffer data structure for dynamic memory buffers. If I end up finishing
this finally, that would change the EAP interfaces from passing in
pointer to u8* and length to using a pointer to struct wpabuf which
would have accessor functions for getting pointers/length for the
included data.
