Hey,
right, it was silly to even ask really ;)
Would I cause considerable harm to the RAM-pool if I allocated the
necessary storage for queueing (basically a linked list node) from it
with a RAW allocation? The packet and node pbufs would be deallocated
together again later-on. The alternative would be to define a limit of
packets to queue up, since space is at premium and I can't add another
heap allocator... Maybe I'm just not seeing the easy solution today ;)
Kind regards
Michael

Yes.
Abusing the pbuf next pointers for my own custom packet queue seemed like a
quick answer,
but I fear that it might backfire quickly...
Not a good idea.
