[PATCH nft 5/7] rule: `list sets' only displays declaration, not definition

[Pablo Neira Ayuso <pablo@netfilter.org>]

 # nft list sets
 table ip nat {
        set libssh {
                type ipv4_addr
        }
 }
 table inet filter {
        set set0 {
                type inet_service
                flags constant
        }
        set set1 {
                type inet_service
                flags constant
        }
        set set2 {
                type icmpv6_type
                flags constant
        }
 }

So in case you want to inspect the definition, you have to use `list set'
and the specific set that you want to inspect:

 # nft list set inet filter set0
 table inet filter {
        set set0 {
                type inet_service
                flags constant
                elements = { 2200, ssh}
        }
 }
