I know it's only two bytes but

  If the outgoing checksum is wrong
  and if offloading is enabled
  and if the checksum field is NOT 0x0000

Would that indicate that your kernel isn't properly clearing memory, and
that you're get a little snapshot of kernel memory for every outgoing
TCP packet?  I have a few captures that show this behavior.
