Felix Fietkau 820f030998 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
