1893 * .param3 and .param4 can be used to mark the allowed range (length for STR
1894 * and value for INT).
1895 *
1896 * For each configuration line in wpa_supplicant.conf, the parser goes through
1897 * this table and select the entry that matches with the field name. The parser
1898 * function (.parser) is then called to parse the actual value of the field.
