nftables 1.0.8 showing invalid type for ip dscp

[Brian Davidson <davidson.brian@xxxxxxxxx>]

The following ruleset setting ct mark from ip dscp does not display
the right-hand expression 'ip dscp' correctly when listing the
ruleset.
It instead displays '@nh,8,8 & 0xfc [invalid type]'.  'ip6 dscp' looks normal.

table inet x {
        chain y {
                type filter hook postrouting priority mangle + 1; policy accept;
                ct mark set ip dscp | 0x40 counter
                ct mark set ip6 dscp | 0x40 counter
        }
}

# nft list table inet x
table inet x {
        chain y {
                type filter hook postrouting priority mangle + 1; policy accept;
                meta nfproto ipv4 ct mark set @nh,8,8 & 0xfc [invalid
type] | 0x40 counter packets 3584 bytes 575402
                ct mark set ip6 dscp | 0x40 counter packets 755 bytes 255731
        }
}
