Oops, sorry - receive. We can only indicate "CHECKSUM_UNNECESSARY", nothing more advanced right now, but right now we'd indicate that if the packet had 0x0000 in the checksum field, but should've had 0xffff. On TX I believe we actually do in HW exactly what your patch just did.
Can you describe the visible effects of this problem ? Is that because of a conversion we might do later to CHECKSUM_COMPLETE ?
