Add three ethernet port but it can not working

I’m not sure what these parameters mean. Is there any relevant document to guide me

Thank you

phys and phy-name just indicate the pcie lane mapping to the hardware.

I add this code to the device-tree , and UPHY8 is work ,but 14140000.pcie and 14100000.pcie is down

pcie@14160000 {
status = “okay”;
vddio-pex-ctl-supply = <&p2888_spmic_sd3>;
nvidia,disable-aspm-states = <0xf>;
nvidia,max-speed = <4>;
phys = <&p2u_8>;
phy-names = “pcie-p2u-0”;

Can you give me some suggest
