There is currently no mechanism exposed by wpa_supplicant to set this,
so you will most likely need to modify source code to either just
hardcode the special string you want for this specific case or to
provide something more generic that could be applicable for multiple
uses. It should be noted that wpa_supplicant needs to be able to control
the cipher list when EAP-FAST is used, so there are some constraints on
what can be done simply with a single call to SSL_CTX_set_cipher_list().
