From 820f03099894bd48638fb5be326b5c551f0f2b98 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 20 Feb 2018 15:58:42 +0100 Subject: netfilter: add a xt_FLOWOFFLOAD target for NAT/routing offload support This makes it possible to add an iptables rule that offloads routing/NAT packet processing to a software fast path. This fast path is much quicker than running packets through the regular tables/chains.
