I'm aware of that link, and sadly the information in that table can at best be described as "confused".
For example, under "Behaviour" it mentions "1GbaseT/100baseT". How exactly does a SFP module exhibit baseT behaviour (which is twisted pair copper ethernet.) Hint: it can't and it doesn't. "Mode" being listed as "TP" is also misleading and wrong. The ethtool value of 0x20 is bit 5, which is 1000baseT_Full which has nothing to do with a SFP (and won't be reported as even a supported mode for this SFP.) Bit 41 would make sense (1000baseX), which is listed against mode 1.
I'm afraid looking at that URL just adds to more confusion.
-- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
