Hi,
I am using OpenWrt 22.03.3 r20028-43d71ad93e on Raspberry Pi Compute Module 4 Rev 1.0 inside WaveShare Dual Gigabit Ethernet 5G/4G Mini-Computer.
Kernel reports

eth1 is also physically connected and both sides of the PHY report a gigabit link.
However, the kernel does not report eth1 being present as a device. Obviously I cannot use it in --> Network --> Interfaces --> Devices.
Can someone help me to understand which step I am missing?
