The lwIP way to solve this is to defin PBUF_LINK_HLEN to be big enough for both sides. We do waste some bytes that way, but it should work. However, I just saw that PPP (new?) seems to allocate many pbufs as PBUF_RAW, which kind of breaks the link-header size calculation and thus might make my suggestion not work... Anyway, we might want to fix this in a generic way...
