Hi Pablo,

I'd like to start playing with those patches in OpenWrt/LEDE soon. I'm
also considering making a patch that adds iptables support.
For that to work, I think it would be a good idea to keep the code that
tries to offload flows to hardware in nf_flow_offload.c instead, so that
it can be shared with iptables integration.

By the way, do you have a git tree where you keep the current version of
your patch set?

Thanks,

- Felix
