netfilter: conntrack: built-in support for DCCP
CONFIG_NF_CT_PROTO_DCCP is no more a tristate. When set to y, connection
tracking support for DCCP protocol is built-in into nf_conntrack.ko.
footprint test:
$ ls -l net/netfilter/nf_conntrack{_proto_dccp,}.ko \
net/ipv4/netfilter/nf_conntrack_ipv4.ko \
net/ipv6/netfilter/nf_conntrack_ipv6.ko
(builtin)|| dccp | ipv4 | ipv6 | nf_conntrack
