Hardware Steering – Connectx6

[Tanay Maheshwari]

Hello,
I have a node with the SmartNIC ConnectX6 – and I am trying to run the NVIDIA GPU Packet Processing application.
However, running the application throws this error

`
mlx5_net: [mlx5dr_table_init_check_hws_support]: HWS not supported, cannot create mlx5dr_table
mlx5_net: [mlx5dr_table_create]: Failed to initialise table
mlx5_net: [mlx5dr_action_validate_hws_action]: Cannot create HWS action since HWS is not supported
<code></code>`

According to the documentation (https://doc.dpdk.org/guides/nics/mlx5.html) HW Steering – NIC ConnectX-5 and before are not supported
That means it should have worked for my ConnectX6 node, right? Am I missing something, or is any additional config required?

If anyone is familiar with this, please help me out! I can’t find any documentation or threads surrounding this on the internet! It would be a great help if anyone could help me figure this out.

Thanks,
Tanay

Hi Tanay,

I wanted to check if this issue is still unresolved. I haven’t had a chance to look into it yet, but I plan to review the documentation and experiment with a few approaches. I’ll share any updates or findings here after the holidays.

Thanks,
Komal

Hi Komal,
It’s still unresolved. Do we have any updates?

Hi Tanay,

Based on the details of the ConnectX-6 from one of the FABRIC VMs and the DPDK documentation you shared (DPDK MLX5 Guide), it appears that the ConnectX-6 available in FABRIC is not supported. We are currently working on integrating new BlueField DPUs, which may provide a suitable solution.

Hi Komal,
Just wanted to check if there is a timeline for integrating the BlueField DPUs.

Hi Tanay,

We are targeting a release for either Summer or Fall and will share more details once our plans are finalized.
