1541 * struct wpa_ssid is stored in .param1. .param2 (if not NULL) is similar
1542 * offset to the field containing the length of the configuration variable.
1543 * .param3 and .param4 can be used to mark the allowed range (length for STR
1544 * and value for INT).
1546 * For each configuration line in wpa_supplicant.conf, the parser goes through

1553 * integer. More complex types will need to use their own parser and writer
