If we would make it accessible via nf_ipv6_ops struct, then the dependency goes away and we could place ipv4 and ipv6 parts in a single module. Just saying, it would avoid adding extra modules. We could then have nf_synproxy.ko # shared code nft_synproxy.ko # nftables frontend xt_SYNPROXY.ko # ip(6)tables frontends
