So that sounds like it is downshifting because it thinks there is a
broken pair. Can you disable downshift? Problem is, that might just
result in link down.

I don't suppose there is a register to restart SGMII sync?  Sometimes
there is.

Anyway, shared reset makes this messy, as you said. Unfortunate
design. But i don't see how you can work around this in the
bootloader, especially the cable plug events.
