Device Tree missing network adapter definition?

As you can see the WAN-port/NIC registers fine with a label from the nanopi-r6c device tree

$ grep fe1c0000 /boot/dtb/rockchip/rk3588s-nanopi-r6c.dtb
grep: /boot/dtb/rockchip/rk3588s-nanopi-r6c.dtb: binary file matches

dmesg:

However the LAN-port does not have such a label in dmesg output.
