That actually seems like a pretty big layering violation (though
eap_wsc.c is somewhat guilty of this).  Why is the EAP method involved
in SSID selection?  EAP methods are usually just authentication code
run after the SSID/BSSID has already been selected, associated with,
and that specific EAP method has been negotiated via 802.1x.

Though I have no idea what you're actually trying to do, it seems like
what you want is to tell the supplicant to clear the blacklist after an
EAP failure, so that it will retry the connection to the SSID/BSSID and
your EAP method will run again.  That can be accomplished through
wpa_cli, the D-Bus interface, or the other control interfaces.

Could you describe a bit more what needs to happen, and then perhaps we
can figure out a cleaner way of doing that?
