Consider a device that doesn't provide the complete checksum for entire Rx packets, but does verify the checksums for several protocols. Now, assuming the HW is capable of verifying TCP checksums - Should the driver calculate the pseudo TCP checksum for such packets and pass those as COMPLETE? Or should it stick to UNNECESSRAY? [Specifically I'm interested for this for the FW gro implementation - it might be possible to mark an entire aggregation as COMPLETE] Thanks, Yuval
