Is there any networking hardware out there that does TCP checksum generation for outgoing packets but doesn't do IP or UDP checksum generation? If not, "-K" might as well imply that IP and UDP checksums aren't valid for outgoing packets, either.

I've checked in a change to make -K suppress IP and UDP checksum checking.
