- * Table of network configuration variables. This table is used to parse each

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