Regardless of what happens in the future, I think the main question is
how this relates to the code that is currently present in the tree. We
already have NDOs for VXLAN offloading, which is about as protocol
specific as you can get. In my mind, this series is strictly an
improvement to what is already there - it pulls all hardware
offloading code out of the various protocol implementations and VXLAN
out of the driver interface. That seems like a pretty nice cleanup to
me.
