It seems my earlier reply to this didn't go to the list, so retrying.
I just posted RFC v3, which is just about complete. The cover letter
also has the location of a github repo which has a simple example
showing the operation. I'm in the process of updating iperf3 as another
sample application.
The packet splitting is done by the NIC hardware. There are Broadcom
and nVidia NICs which have these feature sets. One of my testbeds is
set up and working with Broadcom.
