I am unable to make the kernel correctly setting up the onboard RealTek RTL8211E, even if the DPAA FMAN microcode was correctly loaded (the kernel reports Fman1: Uploading microcode version 106.4.18).

This is the 4.18.10 kernel log https://gitlab.com/oshw-powerpc-notebook/T2080customizations/blob/master/kernel/4.18.10/kernel_4.18.10_debian_sid_serial.log

In the log the following errors appears

fsl_dpaa_mac ffe4e0000.ethernet: of_count_phandle_with_args(/[email protected]/[email protected]/[email protected], fsl,fman-ports) failed

This is the output of the command "mdio list" in u-boot
