I checked the mos.yml for pppos library. It seems, the library is definitely supported for ESP32. I tested and it works.
Just wanted to know if it is supported on other platforms as well, such as ESP8266, STM etc.
I don't see a platforms: tag in its mos.yml, so I assume it's supported on all platforms.
Trying to build for ESP8266 fails with following error:
netif/ppp/ppp.h: No such file or directory
