Hi,

I'm starting to test Zephyr (v2.6) for support of ESP32 features (interested in WiFi and BLE). Right now

I'm looking at trying out wifi. I managed to build and flash the hello world sample successfully and

now I was trying the "wifi" sample (I'm not sure if that is supposed to be work as I understand ESP32 WiFi

is a recent addition).

I enabled ESP32 WIFI SoC support in menuconfig and then it failed to build since it seems ethernet support

needs to be on. After enabling that I got quite a few more errors which I'm not sure how to address:
