1878 * Table of network configuration variables. This table is used to parse each
1879 * network configuration variable, e.g., each line in wpa_supplicant.conf file
1880 * that is inside a network block.
1882 * This table is generated using the helper macros defined above and with
1883 * generous help from the C pre-processor. The field name is stored as a string
1884 * into .name and for STR and INT types, the offset of the target buffer within
1885 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
1886 * offset to the field containing the length of the configuration variable.
1887 * .param3 and .param4 can be used to mark the allowed range (length for STR
1888 * and value for INT).
1890 * For each configuration line in wpa_supplicant.conf, the parser goes through
1891 * this table and select the entry that matches with the field name. The parser
1892 * function (.parser) is then called to parse the actual value of the field.
1894 * This kind of mechanism makes it easy to add new configuration parameters,
1895 * since only one line needs to be added into this table and into the
1896 * struct wpa_ssid definition if the new variable is either a string or
1897 * integer. More complex types will need to use their own parser and writer
