> Admin queue command for shutdown AQ contains a flag to indicate driver unload. However, the flag is always set in the driver, even for resets. It can cause the firmware to consider driver as unloaded once the PF reset is triggered on all ports of device, which could lead to unexpected results.
>
> Add an additional function parameter to functions that shutdown AQ, indicating whether the driver is actually unloading.
