Are you planning on making this available under an open source license?

As long as you are willing to implement the driver interface code
(driver_*.c) in wpa_supplicant, you do not need to use Linux wireless
extensions. As an example, driver_broadcom.c does not use wireless

All data frames (i.e., EAPOL packets) need to be provided to supplicant.
In addition to this, you will need to generate association events
(wpa_supplicant_event() calls with EVENT_ASSOC parameter. Depending on
the driver/firmware implementation, you may have to generate
EVENT_ASSOCINFO events to get WPA IE information from the AssocReq (if
driver/firmware generated it). In addition, wpa_supplicant needs to be
able to get WPA IE from Beacon/ProbeResp frames through the scan
