Hi Jakub, I have a question to consult you.
Some fault information in our patch are not existed in current ethtool extended
link states, for examples:
"Serdes reference clock lost"
"Serdes analog loss of signal"
"SFP tx is disabled"
"PHY power down"
"Remote fault"

Do you think these fault information can be added to ethtool extended link states?

Thanks,
Guangbin
