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 tim= es (~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 woul= d 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. K=C3=B6ry
