2061 * offset to the field containing the length of the configuration variable.
2062 * .param3 and .param4 can be used to mark the allowed range (length for STR
2063 * and value for INT).
2064 *
2065 * For each configuration line in wpa_supplicant.conf, the parser goes through
2066 * this table and select the entry that matches with the field name. The parser
2067 * function (.parser) is then called to parse the actual value of the field.
2068 *
2069 * This kind of mechanism makes it easy to add new configuration parameters,
2070 * since only one line needs to be added into this table and into the
