So, basically, the useful situation is that the sender sends data the receiver doesn't want. Which still sounds like it's the applications that need to be fixed. If the receiver does want all the data, it simply needs to provision enough buffer area so that it can receive at least enough data so that it can seek first to the data it's interested in (inside of it's application buffer) and then go back. It's still one copy in this case. I still see no real use for this feature. Either the data is stored inside of kernel buffers, or user application buffers. And if the data sent is not useful to the receiver, fix the sender to not send the unwanted data. - 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
