John,
The ones moved to peripheral memory are: memp_memory[] and ram_heap[] i.e.
arrays from which lwip allocates memory for pbufs, etc. It is what would
typically peripheral (hardware) do.
var_data[] on the other hand contains thread related data (not buffers).
At the beginning I wanted to save as much as possible, but later as I had
gained some insight I have reconsidered my view.
Other difference is that var_data[] is used in sequential mode which is not
very likely used on devices with low memory.
Please refer to comment #36 and comment #37 for our further conversation with
Sergei.
Thanks for your consideration
Ilija
