Yes, that's the question -- are stateless offloads (plus CRC32C in the CPU etc) going to give good enough performance that the whole TCP offload exercise is pointless? The only issue is that I don't see how to avoid the fundamental 3X increase in memory bandwidth that is chewed up if the NIC can't do direct placement. - R. -- 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
