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(/soc@ffe000000/fman@400000/ethernet@e0000, fsl,fman-ports) failed

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

FSL_MDIO0:

1 - RealTek RTL8211E <--> FM1@DTSEC3

2 - RealTek RTL8211E <--> FM1@DTSEC4

FM_TGEC_MDIO:

0 - Aquantia AQ1202 <--> FM1@TGEC3

1 - Aquantia AQ1202 <--> FM1@TGEC4

12 - Cortina CS4315/CS4340 <--> FM1@TGEC1

13 - Cortina CS4315/CS4340 <--> FM1@TGEC2

This is the output of the command "ping 192.168.1.1" fm_eth_open: MacAddress is multcast address Using FM1@DTSEC3 device

FM1@DTSEC3: Tx error, txbd->status = 0x8800

FM1@DTSEC3: Tx buffer not ready, txbd->status = 0x8800

FM1@DTSEC3: Tx buffer not ready, txbd->status = 0x8800

And this is the output of "printenv" i nu-boot
