Read the RSS NDIS documents from Microsoft. You aren't going to want to demux to more than, say, 256 cpus for single network adapter even on the largest machines. Therefore a simple translation table and/or "base cpu number" is sufficient to only need 8 bits of cpu identification. You will be limited by the number of MSI-X vectors also, for implementations demuxing directly to cpus using MSI-X selection. > That would cover TCP, are there similarly fungible fields in SCTP or > other ULPs?

LRO came out of our own design, the network folks found it reasonable and thus they have started to implement it. The same is true for Microsofts RSS stuff. It's a hardware interpretation, therefore it belongs in a driver API specification, nowhere else. - 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
