I would argue that the meanings are the same on transmit and receive

it's very difficult to know whether you are on the transmit or receive
path.  Personally, I would just remove the warning completely.

I would keep it as it is, I fixed several RHEL kernel bugs exposed by
this warning, it is pretty useful for debugging.

You can just drop the change in the block above and gso_send_check()
will take care of the rest.  Regardless of the state of the incoming
packet, GSO needs the checksum to be reset to CHECKSUM_PARTIAL in
order to work.

Right, makes sense.

I think this is a different problem, unrelated to the checksum issue.
Can you test this patch:
http://git.kernel.org/?p=linux/kernel/git/jesse/openvswitch.git;a=commit;h=d9d59089c43fc33eb403cbb928e56c131f191dd5

I believe it should fix the problem, although there are still a few
lingering reports that I'm trying to track down.

I will try your patch together with my updated patch.

Thanks!
