Is it possible to connect esp32 ethernet RMII to another MCU's ethernet RMII without having to put a PHY chip in between? We are using SPI as an interface between a PIC32 and the ESP32, but looking forward we might want to take advantage of ethernet's faster speeds. Both of the MCUs have RMII interfaces available.
