I see this patch has been abandoned.
I am testing it with a ZynqMP board (macb ethernet) and it seems to more or
less work. It got tx timestamp timeout at initialization but after some times
(~20 seconds) ptp4l manages to set it working. Also the IEEE 802.3
network PTP mode is not working, it constantly throw rx timestamp overrun
errors.
I will aim at fixing these issues and adding support to interrupts. It would be
good to have it accepted mainline. What do you think is missing for that? I see
you faced issues with few Armada SOM and IP_MULTICAST, is it still the case?

I am new to the PTP and Ethernet APIs I will try to not speak nonsense but
please correct me if I do.
