To disable the inband-mode for this 2.5g copper sfp. But have not found a way to set a flag which i can grab in phylink.
The interface imho can only hold 1 value (speedmode which is correctly set to 2500baseX) and the mode holds ethtool options which seem not accessable from phylink.c

I had only the sfp message with vendor/partno and the interface up from mac (2500baseX/Full) But no link up.
Which message(s) do you want to see?
