I have followed design guidence to layout my customer board,but an error occurs in every booting:
“[ 164.608747] Generic FE-GE Realtek PHY r8169-8-100:00: Downshift occurred from negotiated speed 1Gbps to actual speed 100Mbps, check cabling!”
Is there something wrong with my settings?
Could you help to refer the following steps to load downstream driver(r8168) instead of upstream driver(r8169) and check if it could help?
$ sudo su
# cd /lib/modules/5.10.104-tegra/kernel/drivers/net/ethernet/realtek/
# mv r8169.ko r8169_temp.ko
Please also share the dmesg after reboot for further check.
