Intel STV team ran more tests and found a performance regression. I managed to reproduce it, and worked on optimizing the Rx path. I managed to go from -25% to -6% for this use case, but this is still a significant regression so I'll drop this patch. The good news is that the optimization is valid for mergeable buffers case, and it gains 5% so I'll post this optimization instead. Thanks to the STV team for the testing, Maxime
