Hi, 

This series adds the support for mlx5 clock real time translation mode.
In case of no objection the series will be applied to mlx5-next branch.

Device timestamp can be in real time mode (cycles to time translation is
offloaded into the Hardware). With real time mode, HW provides timestamp
which is already translated into nanoseconds.

For more information about real time mode please see last patch in the
series.

Thanks,
Saeed.
