Re: [dpdk-dev] ieee1588fwd.c implementation

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.
