Flow offloading (as implemented in OpenWrt on 4.14) supports both
hardware offload and generic software offload for routing and NAT.
SFE is not necessary anymore.

So you've made a backport of
https://www.kernel.org/doc/Documentation/networking/nf_flowtable.txt to
4.14 in OpenWRT ?
Yes. The OpenWrt version is potted to iptables and achieves something similar 
to SFE. Hence my curiosity.

Hardware NAT of float is only supported in mt7621 currently. qca8k (Some 
atheros switches) will be next I believe. We’ll see.

"of float" = offload, right?
a bit off-topic for this thread but if hw nat offloading is supported on mt7621 whats the requirements for getting it to work?
