The port role can and will suddenly change at run time. Therefore the hardware must time stamp all PTP event messages. Otherwise you have a race condition that cannot be solved. The only hardware I ever saw with this defective design was the IXP 465. That was fifteen years ago. Even at that time, it was clear that the hardware design will not work in real life. I thought that vendors learned from their mistake, because that design quickly went EOL.
