net: sfp: augment SFP parsing with phy_interface_t bitmap
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. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
