1968 * .param3 and .param4 can be used to mark the allowed range (length for STR
1969 * and value for INT).
1970 *
1971 * For each configuration line in wpa_supplicant.conf, the parser goes through
1972 * this table and select the entry that matches with the field name. The parser
1973 * function (.parser) is then called to parse the actual value of the field.
1974 *
1975 * This kind of mechanism makes it easy to add new configuration parameters,
1976 * since only one line needs to be added into this table and into the
1977 * struct wpa_ssid definition if the new variable is either a string or
1978 * integer. More complex types will need to use their own parser and writer
1979 * functions.
