Hi,

I have observed high rates of packet loss when using OVS to "forward"
packets to a GRE or VXNET port. This packet loss does not occur to
anywhere near the same extent when OVS is used to "forward" packets to
a port that does not use tunnelling.

The attached graph loss.pdf illustrates this. It appears that loss starts
at around 500,000pps and increases quite rapidly at that point.

I have also graphed CPU utilisation on the "forwarding" machine.
However it does not seem to be very enlightening.

I have not poked at the code to investigate why this may be occuring and
I am posting to see if this is a known problem.
