... and I have code that implements a library for Marvell PTP, which is
dependent on the timestamping stuff getting sorted. I tested it
recently, and at least the user API wasn't working as intended in
mainline kernels.
When we actually get to a point where we can choose between the MAC and
the PHY timestamper, I'll go back to working on that library. Sadly,
that's not yet.
