Follow-up Comment #7, task #7896 (project lwip):
We're actually working on this. It showed up that we still need to
- fully support a REF type pbuf for RX (fails at least on IPv6 reassembly, I
think)
- need to DMA-align TX buffers (the resulting payload pointers that get sent
on the link). This might be more tricky as it would mean the 'header' of a
pbuf is a different one for UDP/TCP and IPv4/IPv6...
