This patch will be available in the next nftables release. This requires a
kernel >= 5.9-rc1.

    src: support for implicit chain bindings

    This patch allows you to group rules in a subchain, e.g.

     table inet x {
            chain y {
                    type filter hook input priority 0;
                    tcp dport 22 jump {
                            ip saddr { 127.0.0.0/8, 172.23.0.0/16,
192.168.13.0/24 } accept
                            ip6 saddr ::1/128 accept;
                    }
            }
     }

    This also supports for the `goto' chain verdict.

BTW: Thanks for splitting this long report into several reports into
independent bugzilla tickets for easier tracking.
