Linux Kernel net/mlx5e Component MQPRIO Configuration Vulnerability with HTB Offload

A vulnerability in the Linux kernel's net/mlx5e component has been addressed. The issue arose when enabling MQPRIO while HTB offload was already active, causing the driver to return an error and trigger a warning. This behavior led to an unnecessary call trace. The solution involves modifying the code to return a more appropriate response, along with a user-friendly message.

Impact

The vulnerability could lead to improper handling of MQPRIO configuration, causing unnecessary warnings and call traces, which could disrupt normal operations.
