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. Requires Linux 4.14 Signed-off-by: Felix Fietkau <nbd@nbd.name>
