        If this option is enabled, the connection tracking code will
        provide userspace with connection tracking events via ctnetlink.
 
-nf_conntrack_events_retry_timeout - INTEGER (seconds)
-       default 15
-
-       This option is only relevant when "reliable connection tracking
-       events" are used.  Normally, ctnetlink is "lossy", that is,
-       events are normally dropped when userspace listeners can't keep up.
-
-       Userspace can request "reliable event mode".  When this mode is
-       active, the conntrack will only be destroyed after the event was
-       delivered.  If event delivery fails, the kernel periodically
-       re-tries to send the event to userspace.
-
-       This is the maximum interval the kernel should use when re-trying
-       to deliver the destroy event.
-
-       A higher number means there will be fewer delivery retries and it
-       will take longer for a backlog to be processed.
-
 nf_conntrack_expect_max - INTEGER
        Maximum size of expectation table.  Default value is
        nf_conntrack_buckets / 256. Minimum is 1.
