Add two fields to netdev_queue as head_cnt and tail_cnt. head_cnt is
incremented for every sent packet in netdev_tx_sent_queue and tail_cnt
is incremented by the number of packets in netdev_tx_completed_queue.
So then the number of inflight packets for a queue is simply
queue->head_cnt - queue->tai
