Subject: [net-next PATCH 0/3] qdisc bulk dequeuing and utilizing delayed tailptr updates

This patchset uses DaveM's recent API changes to dev_hard_start_xmit(),
from the qdisc layer, to implement dequeue bulking.

Open questions:

- For now set bulk limit to 8 packets, don't want to stress the driver
  avail ring_buffer space.

- We are not doing proper accounting for weight_p/quota in __qdisc_run(). Do we care?

- Is the (!skb->next) check in dequeue necessary?

- Do we need some checks in dev_requeue_skb() as we could be requeuing a SKB list?

 - Should we rename dequeue_skb() to dequeue_skb_list() ?

Based on top of:
 commit 364a9e93243d ("sock: deduplicate errqueue dequeue")
