The Marvell PHY datasheets indicate they support PTP. I've not looked at how they implement it, and if the current model will work.
IIRC, those parts time stamp on the MII bus input, and not in the PHY itself, and so they offer no advantage over MAC time stamping. I suspect that is why there has been so little interest. Thanks, Richard
