Hi,
I am facing an issue with mlx5 with error in "promiscous mode" in MLX5 NIC
card.
The Application initializes successfully and the traffic/packets are not
processed.

Error Snippet Below:

However testpmd works fine here;

I have below questions:
1. Is the error the cause for the traffic not being processed by NIC card?
2. Is there something I have missed here in terms of memory configuration
which is causing not to enable promiscous mode?

Let me know if any addition information is required.

Thanks in advance
Regards
Vikram
