Dear,

Thank you for the information !
I rerun the primary application with the other terminal running pdump,
however it still can't capture the packet.
As for the logs you mentioned that is printed after the primary application
terminates. Also, for the primary application log, I can make sure it
transmits and receives the packet, but pdump still can't capture it.

*- For the log of pdump*

[oran@localhost pdump]$ sudo ./dpdk-pdump --file-prefix wls_1 -- --pdump
'port=0,queue=*,tx-dev=/home/oran/Music/tx.pcap,rx-dev=/home/oran/Music/rx.pcap'



<snip>



Primary process is no longer active, exiting...


Also, do you know whether pdump can capture the virtual function packet or
not ? (We bind to vfio-pci)


Best Regards,

Shu-hua, Liao
