CVE-2025-38039

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Avoid WARN_ON when configuring MQPRIO with HTB offload enabled

When attempting to enable MQPRIO while HTB offload is already configured, the driver currently returns -EINVAL and triggers a WARN_ON, leading to an unnecessary call trace.

Update the code to handle this case more gracefully by returning -EOPNOTSUPP instead, while also providing a helpful user message.
