Yes, this works just fine. In your DSR handler, simply call eth_drv_recv() for every packet that you have buffered up. > I would appreciate your response to my earlier email regarding zero-copy > in XXXX_Recv function as well. Thank you. This is a much harder problem and, sadly, with the current upper layer design, there is no way to accomplish it at this time. It would require a fairly significant restructuring of the middle layer (eth_drv) which sits between the stacks and the hardware drivers. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
