  If you're writing an EAP client, stop now.  Use wpa_supplicant, which works everywhere, and implements everything.

  Writing another EAP client is a*terrible* idea.  It will be vaguely compatible with existing systems, but not completely compatible.  And all of the RADIUS server authors will have to spend time with YOUR customers, explaining why your software is broken.

  Don't write an EAP client.
