Netfilter "Flow offload" / HW NAT

Looks like Linux is finally getting hardware NAT support: http://patchwork.ozlabs.org/cover/852523/ More information here: https://lwn.net/Articles/738214/ The code is new so no drivers will support hardware offloading off the bat. Still, the code is 2.5 times faster than the regular software path. The patch applies cleanly to 4.14 which seems to be the next LEDE/OpenWrt kernel version.

It's coming.
