> Without this patch, the number of queues per i40e VF is defined as 4 by
> CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VF=4 in config/common_base.
> It is fixed value determined in building time and can't be changed during run
> With this patch, the number of queues per i40e VF can be determinated

> with the EAL parameter -w aaaa:bb.cc,queue-num-per-vf=8 , the number of
> queues per VF created from this PF is 8.
> If there is no "queue-num-per-vf" setting in EAL parameters, it is 4 by default
> as before. And if the value after the "queue-num-per-vf"
> is invalid, it is set as 4 forcibly. The valid values include 1, 2, 4, 8, 16 .
