TDA4VM: PCI-E Driver for Gigabit Ethernet

Part Number: TDA4VM

Hi,TI

    We want to using PCI-E Gigabit Ethernet on PCIe Interface on TDA4VM EVM. The module is REALTEK 8111, as follows:

      The sdk we used:08_06_00_12

      1.We can't found pinmux configuration of serdes0/1/2(pcie) in dts in sdk.  Where can I find this?

      2.We heard that  Linux supports PCIe driver for gigabit ethernet after the KERNEL5.0. Is that right?

      3.The module(RTL8111) slot on X2 lane PCIe interface, and using the default system(kernel 5.19). the log as follows:
