Not really related to this patch, but to how it would work with
different drivers/hardware.

In some of our hardware (the ones handled by igc/igb, for example), the
timestamp notification comes some time after the transmit completion
event.

>From what I could gather, the idea would be for the driver to "hold" the
completion until the timestamp is ready and then signal the completion
of the frame. Is that right?
