Quite the contrary, I think a software implementation is a minimum
requirement for inclusion of this feature.
Without a software implementation, there is no clear definition of
what is supposed to happen, and no clear way for people to test those
expectations unless they have the specific hardware.
I completely agree with Jiri. Hardware offload first is _not_ how
we do things in the Linux networking.
