2506 * .param3 and .param4 can be used to mark the allowed range (length for STR
2507 * and value for INT).
2508 *
2509 * For each configuration line in wpa_supplicant.conf, the parser goes through
2510 * this table and select the entry that matches with the field name. The parser
2511 * function (.parser) is then called to parse the actual value of the field.
