[PATCH nft] parser_bison: allow to use quota in sets

[Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>]

src: support for restoring element quota

This patch allows you to restore quota in dynamic sets.

 table ip x {
        set y {
                type ipv4_addr
                size 65535
                flags dynamic,timeout
                counter quota 500 bytes
                timeout 1h
                elements = { 8.8.8.8 counter packets 9 bytes 756 quota 500 bytes used 500 bytes timeout 1h expires 56m57s47ms }
        }

        chain z {
                type filter hook output priority filter; policy accept;
                update @y { ip daddr } counter packets 6 bytes 507
        }
 }
