Well, I think some initialisation is not done - maybe multiplexed pin
setup is missing, maybe some gpio is used to activate something,
unfortunaltelly, no datasheet is available publicly for SoC used :(

No, I disassembled my box and then found datasheets for ICs found on
PCB - that's where I found those IDs. Then I found it looks like
working, however I could not verify it yet, because I did not reached
init launch/userland level yet.

With ethernet working, I would be able to do more (rootfs via nfs),
but this did not happen, yet.

On RB2011, at least some variant, SFP cage is connected here. Mine has
that. However, AR8327 is not recognised here, so this step need wait
until switch presence is detected...
