Hardware:
-ESP32 Pico
-LAN8720 with mode configuration [011] = 100Base-TX Full Duplex. Auto-negotiation disabled.
CRS is active during Receive.

Situation:
The ETH.begin() overrides the Hardware mode configuration.
Why is it so and how can i initialize the Networks with the real Hardware configuration?
