very interesting discussion.. i interested in patches for lwip memory
allocation. as we discussed in the past, to provide zero-copy driver
with some microcontrollers, (i have an arm7 i.e.), we should allocate
in different regions pbufs and pools (in particolar pbuf for rx
i know that in cvs head something has done to have the possibility to
DMA with tcp send, reducing pbuf chains, chancing enqueue... with a
