* Table of network configuration variables. This table is used to parse each
* network configuration variable, e.g., each line in wpa_supplicant.conf file
* that is inside a network block.
*
* 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
* functions.
