一般常见的以太网卡MTU是1500, 那么ESP32的wifi的MTU是多少？

yes, I seethe chapter of SDIO Slave after update "esp32_technical_reference_manual.pdf";

furthermore, I look forward SDIO Slave driver in esp_idf, is there any plan about it?

I plan to use esp32 as SDIO slave, is there any guide to use peripheral SDIO Slave? I have not found any chapter about SDIO slave in book of "esp32_technical_reference_manual.pdf" or SDIO Slave driver in esp_idf SDK.
