The typical use case for the TCP is variable length packets up to a
fixed maximum (6144 bits for LTE). Message passing is inherently a
better fit and the double-mapped buffer probably shouldn't apply.

This is a good point. How would this system deal with variable length packets? The problem I have with message passing is that it becomes too device specific and has additional latencies and limits on how much data can be passed through the message queue.

There are a lot but they all boil down to different forms of message passing. MessageQ is the quickest and fairly easy to use but has limits on the amount of data one can pass.

I think it will be good at the meeting tomorrow to talk about a couple of different approaches. We can lay out a couple of options and poke holes in them to figure out which direction we want to take this.
