The NIC has a descriptor of buffers, the NIC can thus DMA right into this buffer which only contains packet data and nothing else outside of those packets. The software implementation, of course, will not be able to do this and will need to copy. > One thing I would like to see is some generic code for the channels. > It might be interesting to try if that data structure could be used > in other parts of the kernel that pass objects around (like VM or block > layer) Seconded. This should be easy once we have the basic global input queue channel working. I even put it in include/linux/netchannel.h in my vj-2.6 tree sort of to hint at this. :) - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
