I ask a much more basic question: how often do TCP checksums fail?
I rebooted my own Solaris workstation about 3 days ago. It talks a lot
over the exterior Internet. In that time, it has counted two TCP
errors and one UDP error, which are presumably checksum
failures. That's out of about 2 million incoming packets.
