We have tested it in Mellanox lab, non GRO traffic shows some improvement in bandwidth when using the patch, and anyway, the right way is to copy the exact header and not just an arbitrary number of bytes. Also tested using a built-in function (the orignal patch [2]). Eric's solution gives the same numbers (even a bit better).
