Hi Ilya,
Sorry for the late reply. Yes, whatever you suggested is doable. As of now
ovs-bugtool has only dpctl/show command and i think we need to add this command
"ovs-vsctl get interface" to ovs-bugtool. I will float the updated patch ASAP.

Hi Ilya,
Thanks a lot for the explanation. As per your suggestion, I will move all the
counters (including 'tx_retries')to some structure and place a pointer to it
in netdev_dpdk structure so that the padding size will not vary with the
introduction of new counters in future.
