[dpdk-users] Dpdk-pdump fails with error "no ethernet port" when running with Mellanox MCX454A-FCAT nic

[Licj]

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.
