The card can see the entire TCP stream, it doesn't need anything more than that. It can parse every packet header, see what kind of data transfer is being requested or responded to, etc. Look, I'm not going to design this whole friggin' thing for you guys. I've stated clearly what the base requirement is, which is that the packet is fully processed by the networking stack and that the card merely does data placement optimizations that the stack can completely ignore if it wants to. You have an entire engine in there that can interpret an iSCSI transport stream, you have the logic to do these kinds of things, and it can be done without managing the connection on the card. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
