By default the kernel emits all ctnetlink events for a connection. This allows to select the types of events to generate. This can be used to e.g. only send DESTROY events but no NEW/UPDATE ones and will work even if sysctl net.netfilter.nf_conntrack_events is set to 0. This was already possible via iptables' CT target, but the nft version has the advantage that it can also be used with already-established conntracks. The added nf_ct_is_template() check isn't a bug fix as we only support mark and labels (and unlike ecache the conntrack core doesn't copy those). Signed-off-by:
