Merge branch 'net-sched-bulk-dequeue'
Eric Dumazet says:
====================
net_sched: bulk dequeue and deferred drops
First patch adds an additional parameter to ->enqueue() qdisc method
so that drops can be done outside of critical section
(after locks are released).
Then fq_codel can have a small optimization to reduce number of cache
lines misses during a drop event
(possibly accumulating hundreds of packets to be freed).
A small htb change exports the backlog in class dumps.
Final patch adds bulk dequeue to qdiscs that were lacking this feature.
This series brings a nice qdisc performance increase (more than 80 %
in some cases).
