Lars, I did a poor job of answering your question. One of the most important aspects of IP Parcels in relation to TSO and GSO/GRO is that transports get to use a full 4MB buffer instead of the 64KB limit in current practices. This is possible due to the IP Parcel jumbo payload option encapsulation which provides a 32-bit length field instead of just a 16-bit. By allowing the transport to present the IP layer with a buffer of up to 4MB, it reduces the overhead, minimizes system calls and interrupts, etc.
So, yes, IP Parcels is very much about improving the performance for end systems in comparison with current practice (GSO/GRO and TSO). Thanks - Fred
