Ethernet integration

[mrengineer7777]

I have designed and successfully tested a PCB that integrates ESP32 with ethernet.
How do you handle switching between ETH and WiFi?

Details:
ESP32-WROOM-32UE
KSZ8091RNB Ethernet PHY
25Mhz OSC
LAN jack with integrated magnetics and status LEDs
33 ohm resistors on high speed data lines
4 layer PCB with inner ground and power planes.

Currently starting ethernet with ETH.begin(1, 23, 13, 14, ETH_PHY_KSZ8081, ETH_CLOCK_GPIO0_IN, false));
