I have thought for a long time that IP checksumming should and could be
implemented on the network interface hardware. TCP/IP is becoming more
ubiquitous on a minute-by-minute basis and this would seem to make
sense. Does anyone have any reason why this is a BAD idea? Or should we
all start writing letters to 3Com and other manufacturers begging for
this functionality?
It would certainly make life easier for my cute little 66-MHz Pentium
firewall.
