As far as I know, at this point, all types of basechains(arp, ipv4, ipv6, ...)
are unregistered. ingress basechains are already unregistered by
notifier_call(nf_tables_netdev_event) but other types of basechains
still exist in chain list. so that this code is still needed.
But I might have misunderstood about your mention.
If so, please let me know about that.
Thanks!
