These symbols appear within an 'if WIFI' (in drivers/wifi/Kconfig).
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. Dependencies on menus work similarly. There are no
"conditional includes" in Kconfig, so 'if FOO' has no special meaning
around a source. Conditional includes wouldn't be possible, because an
if condition could include (directly or indirectly) forward references
to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

es-WiFi compatible modules use IWIN AT command set.
This driver is split into several layers:
- bus layer: interface to transmit AT commands (SPI, USB, UART...)
- core layer: es-WiFi module management (state, scan...)
- offload layer: TCP/IP offload operations (connect, listen...)
This driver has been tested with stm32l4 disco iot board
(disco_l475_iot1) and the wifi sample:
$ select wifi
$ scan
$ connect "CISCO" 5 password
$ select net
$ tcp connect 192.168.1.21 4242
$ tcp send HelloWorld!
