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
How can I enable this feature?
Thanks very much.
Kind regards, Stefan.
