netfilter: nft_nat: include a flag attribute Both SNAT and DNAT (and the upcoming masquerade) can have additional configuration parameters, such as port randomization and NAT addressing persistence. We can cover these scenarios by simply adding a flag attribute for userspace to fill when needed. The flags to use are defined in include/uapi/linux/netfilter/nf_nat.h: NF_NAT_RANGE_MAP_IPS NF_NAT_RANGE_PROTO_SPECIFIED NF_NAT_RANGE_PROTO_RANDOM NF_NAT_RANGE_PERSISTENT NF_NAT_RANGE_PROTO_RANDOM_FULLY NF_NAT_RANGE_PROTO_RANDOM_ALL The caller must take care of not messing up with the flags, as they are added unconditionally to the final resulting nf_nat_range.
