PPPOS example for ESP32 IDF 4.4.7 esp_netif API

Job ID: 38123955

Budget: $10 – $20 USD

I need a minimal working example of PPPOS in IDF framework v4.4.7.

The requeriments are:

- Minimal example with SIM800L modem.
- Create and configure esp_netif for PPP (create the driver, and task to receive data from modem and send to esp_netif)
- Configure the modem via AT commands (PPP conection ATD*99#)
- After succesfull connection, make a http request for testing.

The most important thing: DO NOT USE esp_modem component. The example must do not use any component, simply the esp_netif API.
