Fix the mv88e6xxx 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. For the record, the semantics of this driver are: flags Meaning ---------------------------------------------------- -------------------------- PTP_ENABLE_FEATURE Time stamp falling edge PTP_ENABLE_FEATURE|PTP_RISING_EDGE Time stamp rising edge PTP_ENABLE_FEATURE|PTP_FALLING_EDGE Time stamp falling edge PTP_ENABLE_FEATURE|PTP_RISING_EDGE|PTP_FALLING_EDGE Time stamp rising edge Cc: Brandon Streiff <brandon.streiff@ni.com> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.
