No it's not airpcap. But they don't want us to disclose their name yet :) I have the driver source code and it does return media type as NdisMedium802_11_Radio if it receives an OID as I mentioned earlier. But the driver never sees a request for those OIDs.
In Wireshark I also tried to add code to send OIDs request to the driver, using wpcap_packet_request(). If I define a new OID on both side, it works fine. However, when I send an OID of OID_GEN_MEDIA_SUPPORTED or OID_GEN_MEDIA_IN_USE, the driver never sees this OID. It's lost somewhere? I still cannot figure out....
