Sorry, I guess I was being dense.

I thought packets were by definition complete... :)

I think you're saying this is one of N fragments
which the minidriver will be re-assembling into
a bigger packet, before somehow passing it up
the stack...

I attach my doc update patch.  (should be the
same as what I sent before.  Consider my apology
for using an attachment as repeated here; my email
setup remains partly broken).  Can you send
a version of your defrag-enabling patch which
applies on top of it, and documents your new
calling convention (with a third return case
for rx_process() too?
