The upstream driver (which is a tarball I found with google AR81Family-linux-v1.0.1.14.tar.gz) has this function ifdefed out. I have a couple of more things I want to test as soon as I have access to the hardware again. If I don't find a better solution I will submit a patch which disables rx checksumming as a whole for inclusion to net-next. Thanks, Hannes
