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.

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.

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.

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