Jetson AGX Xavier PCIe

Hello,

We connected a PCIe network card lan7430 to the PCIe controller 3 of AGX Xavier. We set the status of C3 in the device tree to “okay”, and pinmux is also reused as a PCIe function. But we can’t scan LAN743x with lspci. We can ensure that the LAN743x chip has worked. What configuration does the device tree or cfg file need to do to support C3 external PCIe network card devices?
