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.
