The W5500 + SPI_Slave driver does not work stably.

Sorry for my bad English.

MCU - ESP32 Wroom 32
IDE VSCODE
IDE ESP-IDF 5.1

My device needs to receive data via SPI every 1ms and send it via Eth W5500. Using WiFi instead of W5500, the project works stably.
I have already tested the operation of the W5500 + SPIslave(DMA) for two weeks, so I am providing a short code to find bugs, and not a real project.

Description of the problem: When the SPI_slave (DMA) and the W5500 chip (only the Eth driver, the LWIP library is not used) work simultaneously and transmit packets (any) to the IP address of my ESP32 device, after a certain time a failure occurs:

and so on ad infinitum, the work is very unstable.


I ask for help to solve the problem of unstable operation of the W5500 together with SPI_Slave.
Thank you.

Just for curiosity, have your tried the ethernet basic example? IDF, takes care of inialising W5500.
I used it and never had a problem with it.

"Example Ethernet" also does not work with the SPIslave driver.
From the very beginning, my project was built on "Example Ethernet", and in it I saw that the SPIslave driver and the W5500 driver conflict together.
