Hello Mellanox community, I have an debian-server with an ConnectX-4 card (MCX415A-CCAT, firmware version 12.26.4012). Im using DPDK 19.11.

I try to start l2fwd and other DPDK-software, but i cant start my port:

sudo x86_64-native-linux-gcc/app/l2fwd – -p 0x1

Notice: odd number of ports in portmask.

Cause: rte_eth_dev_start:err=-12, port=0

I would appreciate any help! Thanks a lot!

I see that you are using the Inbox from your OS v5.0-0, can it be reproduced if you are using our Mellanox driver? Downloadable via link:

https://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers

latest driver is 4.7-3.2.9.0.

Also, I see that the port state is down, is this HCA cabled?

Also, did you enable PMD (before dpdk compilation) : vi config/common_base -->enable MLX5_PMD set to yes.
