I had to go through slowly and take lots of Dramamine to get my head to
stop spinning while I read through everything. I agree -- referring to a
frame as a vector when it is not a vector in the sense of the
infrastructure vector makes something relatively straightforward into

Hi Burt,
Thanks, but then I think you mean the vectors as in src/vppinfra/vec.h
but the discussion here was about how the name "n_vectors" is used in
for example src/vlib/node.h and such places. It's a different thing.
If we have a situation like this, now first described using a picture

Hi Dave,
Thanks for your answer, I understand that there are many difficulties
and problems with renaming things in existing code which I did not
realize before.

no law which says that frames need to have 32-bit elements.
Each node decides.

Something has always bothered me about my understanding of VPPs use of the term
"vector" and "vectors". When I think of Vector Packet Processing I think of
processing a vector (array) of packets in a single call to a node. The code,
though, then seems to refer to the individual packets as "vecto
