RTL8111h PCIE LAN connect error on Orin NX

Hi Nvidia,

I’m porting realtek RTL8111h-CG on Orin NX module and our custom carrier board.

The RTL8111h-CG is connected PCIe2 x1 (C7).

I modify the dts file tegra234-p3509-a02-pcie.dtsi to add:

pcie@141e0000 { /* C7x1 node */

status = “okay”;

phys = <&p2u_gbe_0>;

phy-names = “p2u-0”;

};

The lspci：

As you can see the new RTL device 0007:01:00.0 load normally.But when I insert the net cable to ping, it reports a connect error log below.
