[lwip-users] Alignment issue in pbuf

[Midnight Xiong]

Hi,

I have used LwIP 1.3.1 with dm9000a. But I found that if the length of mediate pbuf node is not aligned to 2 (I use 16bit mode for dm9000a), the transmission will be failed. (I have not copied each node buffer of pbuf chain to a big buffer) If I don't want to copy these node buffer to a big buffer, how can I avoid this issue? Can I modify some options of lwip to do it? Thanks.
