Hi John, I got PTP working and was able to transmit a valid PTPv2 packet over the DPDK network card.
Every time a PTP packet arrives I get following message in the testpmd application: Port 0 Received PTP packet not filtered by hardware However, the hardware does not change the timestamp, when I check the received packet. How can I enable this feature? Thanks very much. Kind regards, Stefan.
