We currently parse the SFP EEPROM to a bitmap of ethtool link modes, and then attempt to convert the link modes to a PHY interface mode. While this works at present, there are cases where this is sub-optimal. For example, where a module can operate with several different PHY interface modes. To start addressing this, arrange for the SFP EEPROM parsing to also provide a bitmap of the possible PHY interface modes.
