The typical definition of TOE is "offload 90+% of the net stack", as opposed to "TCP assist", which is stuff like TSO.


I think a better goal is "offload 90+% of the net stack cost" which
is effectively what TSO does on the send side.


A better goal is to not bother with TOE at all, and just get multi-core processors with huge memory bandwidth :)

Again, the point of my message is to have something _positive_ to tell people when they specifically asked about TOE. Rather than "no, we'll never do TOE" we have "it's possible, but there are better questions you should be asking"
