Hi,

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.

I built dpdk-dumpcap utility with debug enabled in meson in dpdk.22.11 and copied dpdk-dumpcap to the VM running our application. 

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”.

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?
