The SFF specification for Direct Attach cable detection has now been ratified. Previously, DA cable detect was looking at the Twinaxial bit in byte 9 of the SFP+ EEPROM. The spec now defines active and passive DA cables in byte 8 of the SFP+ EEPROM. This patch changes the cable detection for both 82598 and 82599 SFP+ adapters to conform to the new spec.
