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.
