Follow-up Comment #6, bug #51908 (project lwip):

I think you can still use PBUF_RAM here, we just need to choose a
pre-allocated size and maybe introduce a define for it.  See
pppos_output_append() where it uses PBUF_POOL_BUFSIZE to determine the maximum
size

>From what I can tell, there's nothing about PBUF_POOL_BUFSIZE that is specific
to pppos. The author must have chosen it rather than introduce a new mechanism
