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.

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