NAME

gen_new_estimator - create a new rate estimator

SYNOPSIS

int gen_new_estimator(struct gnet_stats_basic_packed * bstats, struct gnet_stats_basic_cpu __percpu * cpu_bstats, struct net_rate_estimator __rcu ** rate_est, spinlock_t * stats_lock, seqcount_t * running, struct nlattr * opt);

ARGUMENTS

struct gnet_stats_basic_packed * bstats

basic statistics

struct gnet_stats_basic_cpu __percpu * cpu_bstats

bstats per cpu

struct net_rate_estimator __rcu ** rate_est

rate estimator statistics

spinlock_t * stats_lock

statistics lock

seqcount_t * running

qdisc running seqcount

struct nlattr * opt

rate estimator configuration TLV

DESCRIPTION

Creates a new rate estimator with &bstats as source and &rate_est as destination. A new timer with the interval specified in the configuration TLV is created. Upon each interval, the latest statistics will be read from &bstats and the estimated rate will be stored in &rate_est with the statistics lock grabbed during this period.

Returns 0 on success or a negative error code.
