Re: [PATCH nf-next] netfilter: flowtable: separate replace, destroy and stats to different workqueues

Currently the flow table offload replace, destroy and stats work items are
executed on a single workqueue. As such, DESTROY and STATS commands may
be backloged after a burst of REPLACE work items. This scenario can bloat
up memory and may cause active connections to age.

Instatiate add, del and stats workqueues to avoid backlogs of non-dependent
actions. Provide sysfs control over the workqueue attributes, allowing
userspace applications to control the workqueue cpumask.

I'm going to apply this to nf-next, it should be possible to revisit
this problem incrementally.

Applied, thanks for your patience.
