> phylink pool SFP loss signal to determine link up/down?
Yes, the SFP driver will act on a GPIO for link up/down, and a GPIO for module prescience. When it detects an SFP module hotplugged, it reads the EEPROM to find out what sort of module it is, and what mode should be used between the MAC and SFP module. It will also handle if the SFP module is copper, and has a PHY in it...
