We can use pbuf directly for zero-copy implementation with DMA but in some system DMA required aligned buffer. However the lwip aligns the buffer relative to the layer offset and begin of payload buffer remains unaligned. This patch add alignment option with 2 cases. First case, default, preserves current behavior. Second case is changed payload alignment to begin of payload buffer alignment. |
