Ugh. Yet another hook :-( One would think we have enough by now. In any case, I still think this ILA translation stuff should either go into xtables (NPT-ish), nftables, or into tc if nft is unusable for whatever reeason. Judging by where this hook is placed, nf hooks would work just fine. If the iptables traverser has too high cost (unfortunately, xtables design enforces counters and iface name matching even if its not wanted/unneeded for instance), maybe nft would perform better in that regard. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
