you are right. mbufs are used for buffer management in the BSD stack. sk_buff as the linux equivalent . basically they are chains with control information and data. but i think linux assuming more memory allocated a large sk_buff and hence data and headers are contiguous. I remember Alan Cox giving some explanation for why it was this way. For more info you can search in google.For info on mbuf refer rich stevens TCP/IP vol 2 Quoting Aleksander Rozman <[EMAIL PROTECTED]>:
