gred_enqueue(), bfifo_enqueue() and plug_enqueue() admit a packet when the
current backlog plus the packet length fits within the queue limit:

  sch->qstats.backlog + qdisc_pkt_len(skb) <= sch->limit (gred default VQ)
  gred_backlog+qdisc_pkt_len(skb) <= q->limit  (gred configured VQ)
  sch->qstats.backlog + qdisc_pkt_len(skb) <= sch->limit (bfifo)
  sch->qstats.backlog + skb->len <= q->limit             (plug)
