stable inclusion from stable-5.10.80 commit d833ddddec5b1ff44f2c241bf92361e87b228f53 bugzilla: 185821 https://gitee.com/openeuler/kernel/issues/I4L7CG
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 59a8bda062f8646d99ff8c4956adf37dee1cb75e ]
While networking works fine in RGMII mode when using the Linux generic PHY driver, it fails when using the Atheros PHY driver. Fix this by correcting the Ethernet PHY mode to RGMII-RXID, which works fine with both drivers.
