	 * String with field-value pairs, e.g., "peapver=0" or
	 * "peapver=1 peaplabel=1".
	 *
	 * 'peapver' can be used to force which PEAP version (0 or 1) is used.
	 *
	 * 'peaplabel=1' can be used to force new label, "client PEAP
	 * encryption",	to be used during key derivation when PEAPv1 or newer.
	 *
	 * Most existing PEAPv1 implementation seem to be using the old label,
	 * "client EAP encryption", and wpa_supplicant is now using that as the
	 * default value.
	 *
	 * Some servers, e.g., Radiator, may require peaplabel=1 configuration
	 * to interoperate with PEAPv1; see eap_testing.txt for more details.
	 *
	 * 'peap_outer_success=0' can be used to terminate PEAP authentication
	 * on tunneled EAP-Success. This is required with some RADIUS servers
	 * that implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
	 * Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode).
	 *
	 * include_tls_length=1 can be used to force wpa_supplicant to include
	 * TLS Message Length field in all TLS messages even if they are not
	 * fragmented.
	 *
	 * sim_min_num_chal=3 can be used to configure EAP-SIM to require three
	 * challenges (by default, it accepts 2 or 3).
	 *
	 * result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
	 * protected result indication.
	 *
	 * fast_provisioning option can be used to enable in-line provisioning
	 * of EAP-FAST credentials (PAC):
	 * 0 = disabled,
	 * 1 = allow unauthenticated provisioning,
	 * 2 = allow authenticated provisioning,
	 * 3 = allow both unauthenticated and authenticated provisioning
	 *
	 * fast_max_pac_list_len=<num> option can be used to set the maximum
	 * number of PAC entries to store in a PAC list (default: 10).
	 *
	 * fast_pac_format=binary option can be used to select binary format
	 * for storing PAC entires in order to save some space (the default
	 * text format uses about 2.5 times the size of minimal binary format).
	 *
	 * crypto_binding option can be used to control PEAPv0 cryptobinding
	 * behavior:
	 * 0 = do not use cryptobinding
	 * 1 = use cryptobinding if server supports it (default)
	 * 2 = require cryptobinding
