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.
