Great! Thanks for that hint. I'll have a look at this soon. So you'll
want to integrate the TNC Server directly into the EAP Module, or to
be more precise, you'll add a "TNC Type Module" to the EAP module?

That's good news for me!

So basically, the "only thing I need to do" when I want to perfom
EAP-TNC is to create a IMC/IMV pair and integrate the IMC to
wpa_supplicant and the IMV to Free Radius?
