PTP time scale flag is not compatible with Meineberg
While using WRS v5.0.1 as PTP master L2, two-steps with Meineberg device
we see that the UTC time in Meineberg does not handle well leap seconds
as it should. (This works well with other PTP master).
It seems that we are missing to se to true the PTP timescale flags and
so the slave device don't recognize the TAI/UTC conversion.
