High-level question. How realistic is sending a 40-segment frame in the first
place? This whole thing seems kind of academic to me unless I missed
something.
I usually use 2K pktmbufs and I don't think this is an uncommon size. Most
jumbo frame hardware only does 9.5KB max frame size or so.
So I am having a hard time imagining how I'd end up with more than 10 segments
as a worst-case scenario.
Matthew.
