Sorry, I don't have any docs on this device. Perhaps Dave has the docs which can tell us what RXDCTRL_TCPCSUM actually returns? I assume it returns the correct checksum ending at the IP packet boundary and only goes wrong when extra padding exists. Hmm, I suppose the question then is what exactly does it do if the packet isn't an IP packet?
