Are the drivers from the kernel tree? We have reports from
such checksum problems with the Intel's E100 driver and we still
don't know where is the problem. This driver supports hardware
checksuming, may be in CHECKSUM_HW form for the tested NIC. I still
don't know whether they (the hw csuming) should work only for IA64,
I'm reading their man page.

If these NIC drivers work with 0.9.4 then I really don't
know where is the bug in IPVS 0.8.*. You better to use 0.9.4.
With all these traps in the networking code, LVS should always receive
CHECKSUM_NONE packets and so LVS is forced to make full packet check
in LOCAL_IN. For the E100 driver a bad checksum results. So, I'm
waiting for your feedback. I'm not able to debug the problem without
such NIC. May be Ratz?
