Hi, I do not have a CX6-LX NIC, or any other Mellanox NICs that support switchdev, so I cannot reproduce the problem. I only have a CX3 which works well with OVS-DPDK.

If possible, please try running OVS-DPDK using another Linux distro, and see if the NIC can be used in this case. This will help us find out if it's an issue with OVS-DPDK, or an issue with packaging in nixpkgs.

You could also try unstable, which is newer (3.4) than what stable has (3.3)

Hi, CX6 legacy mode work fine,too.

I tried it in ubuntu 24.04, inbox mlx5_core and repo ovs-dpdk, it work fine.
