<p class="MsoNormal"><span lang="SV">Hi!<o:p></o:p></span></p>
<p>I am using a Intel E810-XXVDA4 and DPDK version 19.11. During troubleshooting we have captures outgoing traffic with dpdk-pdump:<o:p></o:p></p>
<p><code><span style="font-size:10.0pt">dpdk-pdump -- --pdump 'port=1,queue=*,tx-dev=/tmp/tx.pcap</span></code><o:p></o:p></p>
<p>I have opened the pcap-file in wireshark and I can see that some packets are delayed. However, system behavior indicates that the delays I see in the pcap file are not correct, they are too big. My questions is, how is the timestamp on packets in the pcap
from dpdk-pdump created, like NIC HW generated, CPU time at disk write etc. or something else? Are there any run-time or build-time options to change the source of the timestamps?<o:p></o:p></p>
