netfilter: built-in NAT support for UDPlite
CONFIG_NF_NAT_PROTO_UDPLITE is no more a tristate. When set to y, NAT
support for UDPlite protocol is built-in into nf_nat.ko.
footprint test:
(nf_nat_proto_) |udplite || nf_nat
--------------------------+--------++--------
no builtin | 408048 || 2241312
UDPLITE builtin | - || 2577256
