Is there an actual problem you were trying to debug?

My bet is you're using a network interface that offloads checksum
calculations onto the hardware (so it's random data when tcpdump
or ethereal looks at it).

You might notice the DHCP packets' checksums are OK because ISC DHCP
writes those raw.  But it doesn't touch checksums on TCP connections.
