mDNS and W5500 Ethernet chip for ESP32-S3

[mgoeller]

Hi

We have so far used ESP32 (with LAN8720), but now upgraded to ESP32-S3 using W5500 for a wired Ethernet connection. W5500 is officially supported by ESP-IDF and the connection works perfectly for all tasks except mDNS multicast packets. Using Wireshark we can clearly see that the packets are transmitted using the WiFi interface, but not when using a wired connection.

Can you please help?
