O.k., understood. But the receiving router verifies the checksum of
incoming packets and sends them on the firewire link. On firewire we
have CRC checksums to ensure the integrity of packets.
I agree with your patch but I don't see why we should check them in the
driver. I thought your patch will ensure that the checksums will be
verified in the upper layers.
