I'm afraid it does:

enum cntl_msg_types {
        IPCTNL_MSG_CT_NEW,
        IPCTNL_MSG_CT_GET,
        IPCTNL_MSG_CT_DELETE,
        IPCTNL_MSG_CT_GET_CTRZERO,
        IPCTNL_MSG_MAX
};

This is totally broken of course since it also uses netlink_ack(),
netlink_dump() etc. :( Any smart ideas how to fix this without
breaking compatibility?
