fq.h: Port memory limit mechanism from fq_codel

2016-09-30T11:29:21Z

The reusable fairness queueing implementation (fq.h) lacks the memory usage limit that the fq_codel qdisc has. This means that small devices (e.g. WiFi routers) can run out of memory when flooded with a large number of packets. This ports the memory limit feature from fq_codel to fq.h.

fq: split out backlog update logic

2016-04-28T21:03:38Z

mac80211 (which will be the first user of the fq.h) recently started to support software A-MSDU aggregation. It glues skbuffs together into a single one so the backlog accounting needs to be more fine-grained. To avoid backlog sorting logic duplication split it up for re-use.

fq: add fair queuing framework

2016-04-25T20:45:53Z

This works on the same implementation principle as codel*.h, i.e. there's a generic header with structures and macros and a implementation header carrying function definitions to include in given, e.g. driver or module. The fairness logic comes from net/sched/sch_fq_codel.c but is generalized so it is more flexible and easier to re-use. Signed-off-by: Michal Kazior Signed-off-by: David S. Miller
