More to the point, why is the kernel evaluating these as bad checksums?
Is there anyway to recognize these sorts of messages beforehand, so the
kernel knows the checksum is invalid/special. I'm not all the familiar
with the protocols in question, but it seems to me that this is really an
erroneous error message (from the department of redundancy department).

OTOH, it may not be worth the extra code, and there is something
interesting about knowing when all machines on your LAN boot up. Thank
goodness UNH did a decent job sub-netting though, or I would *really* be
inundated with these messages. Windows boxes make a lot of DHCP request,
presumably because they are always rebooting.
