stable inclusion from stable-5.10.80 commit a903984385175d5e074963d8a97736dff1100bb9 bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG

--------------------------------
[ Upstream commit 55dd7e059098ce4bd0a55c251cb78e74604abb57 ]
Commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config") sets the RX/TX delay according to the phy-mode property in the device tree. For the A20-olinuxino-lime2 board this is "rgmii", which is the wrong setting.
Following the example of a900cac3750b ("ARM: dts: sun7i: a20: bananapro: Fix ethernet phy-mode") the phy-mode is changed to "rgmii-id" which gets the Ethernet working again on this board.
