Fix the igb PTP support to explicitly reject any future flags that get added to the external timestamp request ioctl. In order to maintain currently functioning code, this patch accepts all three current flags. This is because the PTP_RISING_EDGE and PTP_FALLING_EDGE flags have unclear semantics and each driver seems to have interpreted them slightly differently. This HW always time stamps both edges: flags Meaning ---------------------------------------------------- -------------------------- PTP_ENABLE_FEATURE Time stamp both edges PTP_ENABLE_FEATURE|PTP_RISING_EDGE Time stamp both edges PTP_ENABLE_FEATURE|PTP_FALLING_EDGE Time stamp both edges PTP_ENABLE_FEATURE|PTP_RISING_EDGE|PTP_FALLING_EDGE Time stamp both edges Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.
