In this PR, regarding IP header checksums, it's stated that a checksum of
0 is specified by the standard to be transmitted as all-1s (0xFFFF). (A
checksum of all 0s is taken to mean that the transmitting host did not
calculate a checksum.)
Can anyone find a reference to this in the official docs, or perhaps find
an explanation why we do indeed send 0'ed checksums? I've replicated this
behavior on both 3.4-STABLE and 4.0-CURRENT, i386 and alpha.
Thanks,
Chuck
