> I40e VF driver uses the num_queue_pairs in vf structure to construct queue
> index look up table. When the nb_rx_queue is less than nb_tx_queue,
> num_queue_pairs is equal to nb_tx_queue. It will make the table use invalid
> queue index, then application cannot poll packets on these queues.
>
> This patch also moves the inline function i40e_align_floor from i40e_ethdev.c to
> i40e_ethdev.h.
