BPI-R4: Copper SFP issues

[Martin Schiller]

Hi!

I've got some issues bringing up copper SFPs in a BananaPi BPI-R4 runnig
the latest OpenWrt master. Using the original Firmware pre-installed on
the BPI-R4 makes the modules work as expected:

I've tested with a HPE J8177C 1GBASE-T module as well as with a FS
SFP-10G-T module.

Any ideas what could be wrong here?

Here are the debug log outputs:
