The driver evenly distributes them across all the ports belonging to the PF. However, some ports may need more queues than others and this equal distribution scheme prevents accessing these other ports unused queues. So, remove the equal distribution scheme and allow the ports to allocate as many queues as they need. Also remove the hardcoded 64 max limit on queue allocation. Instead, use the max limit given by firmware.
