WebJul 17, 2024 · Assuming you have compatible SFP-T transceivers, Yes. An SFP (+) port requires a PHY module unless it's used with a direct-attach cable (DAC) that has fixed SFP+ modules at its ends. Not all SFP/SFP+ ports support 1000BASE-T modules. Quite a few SFP+ ports don't support 10GBASE-T (and if they do the reach is normally reduced to 30 m or so). WebThis function follows this protocol: static void adjust_link (struct net_device *dev); Next, you need to know the device name of the PHY connected to this device.
