Yep, I looked at the most recent version on github and noticed the
cleanup in the Performance Tuning section.

Do you have any numbers of which level of performance can be expected
for the described setup? Theoretical max. for 64 Byte packets is around
14 Mpps. Has anybody observed performance close to this in OpenvSwitch
We were able to get around 14 Mpps using the l2fwd example app from dpdk.
We also re-tested our setup with OVS master (from github) and DPDK 2.1
and found no difference to the results described in my first posting.
