HW support of PTP/timesync solutions in network PHY chips can be

Allow ptp device drivers to provide user with control over the timestamp
latch point.

I just wonder should we add ethtool interface to control this feature.
As we are adding it for phy devices, it's good idea to have a way to
control it through eth device too. WDYT?
Seems doable, I guess somehow expand the controllability being added right
now with this series:
https://lore.kernel.org/netdev/[email protected]/#r
Or some other idea?
Yeah, the series mentioned correlates with your work, that's why I asked
about it.
It would be great to be sure that the interface you are proposing can be
reused or somehow combined with the series.
