Hello,

I am working on a project that requires utilizing WiFi for a mesh network and Ethernet for connecting the ESP32 to another device via ModBus TCP simultaneously. In the Modbus TCP example, I am utilizing netif, and my WiFi solution also employs netif. Is it possible to use netif for both networks and how can I ensure their independent operation?

Sincerely.

This happen when i comment code's part associated with netif on ModBus TCP implementation code.
