Hi all, 

I have run dpdk testpmd successfully with Mellanox MCX454A-FCAT nic(mlx5 driver). I can capture the dpdk packets on the recv side using tcpdump. But the througput does not reach line rate(24gbps throughput with 40gbps line rate).


 Then I want to capture packets on the send side using dpdk-pdump. But the dpdk-pdump failed with error "No Ethernet ports - bye".
The initial info with dpdk-pdump shows that it only probes ixgbe driver and 2 Intel nics But not Mellanox nic. 


Anyone knows why and how to solve it? Thank you.

Mellanox DPDK drivers are not enabled by default in the build.
You need to have rdma-core installed and enable it in the DPDK build config file.

Thank you.


I have enabled Mellanox mlx5 driver and recompiled dpdk. The testpmd is running ok.


The problem is dpdk-pdump can't run with testpmd.
