         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.
