This correct. The loopback interfaces has the no checksum flag
set so we only provide a partial checksum on output (i.e., the
pseudoheader without the payload).
We even export this to user-space via a flag. So you should fix
tcpdump to read this flag and ignore the checksum.
Thank you for the information. Is there any easy way to turn them on? I
need it for LVS.
