Ethernet MAC engine on ESP32 doesn't feature a flow control logic.
|

The MAC driver can perform a software flow control if you enable this option.
|

Note that, if the RX buffer number is small, enabling software flow control will
|
|
cause obvious performance loss.

W5500 is a HW TCP/IP embedded Ethernet controller.
|

TCP/IP stack, 10/100 Ethernet MAC and PHY are embedded in a single chip.
|

However the driver in ESP-IDF only enables the RAW MAC mode,
|

making it compatible with the software TCP/IP stack.

Say yes to enable W5500 driver.
