Thank you very much. The existence of the 'switchdev' driver / framework
is what lead me to think about this, so I might get to work on trying it
The hardware NAT issue seems much more complicated, as there seem to be
a lot of questions to be answered about integration (or not) with
netfilter. I have no particular opinion on this, and will be focusing
100% on the layer2 functionality to begin with.
I'll look closely at the "bridge fdb offload" post you mentioned as this
seems like a cool integration to start with.
Thanks for the links!
