1531 * Table of network configuration variables. This table is used to parse each
1532 * network configuration variable, e.g., each line in wpa_supplicant.conf file
1533 * that is inside a network block.
1535 * This table is generated using the helper macros defined above and with
1536 * generous help from the C pre-processor. The field name is stored as a string
1537 * into .name and for STR and INT types, the offset of the target buffer within
1538 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
1539 * offset to the field containing the length of the configuration variable.
1540 * .param3 and .param4 can be used to mark the allowed range (length for STR
1541 * and value for INT).
1543 * For each configuration line in wpa_supplicant.conf, the parser goes through
1544 * this table and select the entry that matches with the field name. The parser
1545 * function (.parser) is then called to parse the actual value of the field.
1547 * This kind of mechanism makes it easy to add new configuration parameters,
1548 * since only one line needs to be added into this table and into the
1549 * struct wpa_ssid definition if the new variable is either a string or
1550 * integer. More complex types will need to use their own parser and writer
