Subject: [PATCH net-next 0/5] net_sched: sch_fq: round of optimizations

This series is focused on better layout of struct fq_flow to
reduce number of cache line misses in fq_enqueue() and dequeue operations.

Eric Dumazet (5):
  net_sched: sch_fq: avoid touching f->next from fq_gc()
  net_sched: sch_fq: change fq_flow size/layout
  net_sched: sch_fq: use bulk freeing in fq_gc()
  net_sched: sch_fq: do not call fq_peek() twice per packet
  net_sched: sch_fq: perform a prefetch() earlier
