MGBE For Switch：内核报错drivers/net/phy/phy.c:955 phy_error+0x20/0x70

Hi, nvidia。

AGX Orin custom 单板的MGBE0接了MAC_88E6191X交换芯片，修改source/hardware/nvidia/t23x/nv-public/tegra234-p3737-0000+p3701-0000.dts

we don’t have the experience with etherent switch, if pinmux is also correct, please check with the switch vendor what else is needed to be configured.

跟pinmux有关系吗？AGX Orin 64G carrier board也是UPHY_TX06_P这组信号接了10GBE SFI，是不是只修改dts的ethernet@6800000，参考Jetson AGX Orin Platform Adaptation and Bring-Up — NVIDIA Jetson Linux Developer Guide 1 documentation

已经参考Ethernet Controller Configuration的For Switch修改了，把phy也改为phy-fixed模式，为什么还报phy error错误

Failed to poll MAC Software reset原因分析和问题解决

I encountered this issue while debugging ORIN’s 2310000 Ethernet RGMII and repeatedly searched forums and websites without finding the cause. After communicating and debugging with the switch manufacturer, I finally found the cause of the problem. It is because the switch chip needs to be initialized, and after the initialization of the switch is completed, an RX clock will be issued. The MAC driver of ORIN needs the RX clock of the switch to complete the initialization correctly, and a TX clock…
