Robert, how it works? Is there some detection which source port (SFP or
WAN) should be activated? And what happens if you plug SFP module and
also 1G WAN at the same time?

Now I spotted this. Why is PERST# pin configured into gpio mode? Is
there some issue that this pin in pcie mode is not working properly,
that PCIe controller cannot handle it correctly? Or something else?
