Follow-up Comment #25, bug #11400 (project lwip):
re comment #24:
I think you can't simply copy only one PBUF_REF part of a packet since that
would include changing the ->next pointers of the other parts of the packet.
This would only work if the PBUF_REF was the first pbuf in the packet, which
it never will be since all headers (IP / TCP / UDP) are allocated from _RAM
at send time.
Regarding the PBUF_POOL: I think it's a good idea to reserve this for
receiving in order not to block memory by tx needed to receive ACK frames,
for example. Different sized pools including some low-water-mark for RX would
be better (in fact, I'm using those pools, also not with the low-water-mark,
for now. But I think we already had that on lwip-users...)
But as long as it's that way, I'm sticking to PBUF_RAM for this solution.
