+ * 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
