From time to time, very seldom, I encounter damaged TCP traffic, for example: - a mail reaches the next SMTP hop with garbage in the body; - fetching a page with HTTP brings up a message about 'bad HTTP request' with some random chars; - on 'scp' traffic it stops with a message about 'bad MAC addr'; Is this a known issue with the iwi driver/firmware? How is it possible that higher layer (TCP) does not detect this problem in the TCP-checksum stored in the header?
