hi, i applied the same fix in u-boot for M2-Ultra (R40).

Everything about this issue is known. In the meantime, you can use any of these workarounds/fixes: 1. Apply DT fix: https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/ linux.git/commit/?h=sunxi/fixes- for-5.10=8c9cb4094ccf242eddd140efba13872c55f68a87 2. Revert commit bbc4d71d63549bcd003a430de18a72a742d8c91e 3. disable Realtek PHY driver in your kernel. It should still work trough generic PHY driver.

The Banana Pi still doesn't work properly in kernel 5.9.6. I am not in a position to check schematics and to fix DTs. Look at git log for arch/arm/boot/dts/sun7i-a20-bananapi.dts, that would be you, Chen-Yu Tsai and Maxime Ripard. Is there anything I can do to help debugging?

It used to be that we used "rgmii" for all RGMII PHYs. Turns out there are four modes of RGMII, depending on whether the MAC or PHY enable TX / RX signal delays. Most boards in sunxi are designed so that the PHY is providing both TX and RX delays, which is done by pulling up the TXDLY and RXDLY pins at power up. The commit "net: phy: realtek: fix rtl8211e rx/tx delay config" fixes the PHY driver so that it will correctly "reconfigure" the PHY to the requested mode. Previously this was not happening due to incorrect register definitions. To summarize, the PHY driver fix exposes errors in our DTs.
