Subject: [PATCH net-next 0/4] net_sched: sch_fq: add WRR scheduling and 3 bands

As discussed in Netconf 2023 in Paris last week, this series adds
to FQ the possibility of replacing pfifo_fast for most setups.

FQ provides fairness among flows, but malicious applications
can cause problems by using thousands of sockets.

Having 3 bands like pfifo_fast can make sure that applications
using high prio packets (eg AF4) can get guaranteed throughput
even if thousands of low priority flows are competing.

Added complexity in FQ does not matter in many cases when/if
fastpath added in the prior series is used.

Eric Dumazet (4):
  net_sched: sch_fq: remove q->ktime_cache
  net_sched: export pfifo_fast prio2band[]
  net_sched: sch_fq: add 3 bands and WRR scheduling
  net_sched: sch_fq: add TCA_FQ_WEIGHTS attribute
