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.
