Dear all,

Currently, I want to use pdump to capture our DPDK application, however for
the pdump side, unfortunately, didn't capture any packet, also pdump didn't
print any error. While for our application, it also didn't print any log
related to pdump.
*- Here's the log of pdump*
[oran@localhost pdump]$ sudo ./dpdk-pdump --file-prefix wls_1 -- --pdump

primary ##### PDUMP DEBUG STATS ##### -packets dequeued: 0 -packets
transmitted to vdev: 0 -packets freed: 0

*- Here's the detailed step using pdump*
1. Add rte_pdump_init() and rte_pdump_uninit() to our application
2. Recompile DPDK 19.11
3. Add the library, -lrte_pdump & -lrte_pmd_pcap to our application's
Makefile
4. Bind the virtual function for DPDK port (vfio-pci)

Does I miss something? Or does pdump can not capture the virtual function
packet ?
I will be grateful for any help you can provide.

Best Regards,
Shu-hua, Liao
