<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">I am looking to debug my issue with dpdk and E810 NIC for transmit with GRE header. The dpdk-dumpcap utility is my focus to see what dpdk is transmitting. I have carefully studied the mbufs for the packet and looks correct.<o:p></o:p></p>
<p class="MsoNormal">I built dpdk-dumpcap utility with debug enabled in meson in dpdk.22.11 and copied dpdk-dumpcap to the VM running our application.
<o:p></o:p></p>
<p class="MsoNormal">Our application is using the same version of dpdk 22.11 and built with static libraries. Also rebuilt our application with the EAL argument of “proc-type=primary”.<o:p></o:p></p>
<p class="MsoNormal">When I run dpdk-dumpcap I get errors for RTE_FIB tailq. I don’t understand this error, why tailq for RTE_FIB is not created in the dpdk-dumpcap application. Do I need the RTE_FIB for packet capture, can I bypass the need for RTE_FIB?
