It is based on the length of history that is stored about an
rxq (currently 1 min).
$ ovs-appctl dpif-netdev/pmd-rxq-show
pmd thread numa_id 0 core_id 4:
isolated : false
port: dpdkphy1 queue-id: 0 pmd usage: 70 %
port: dpdkvhost0 queue-id: 0 pmd usage: 0 %
pmd thread numa_id 0 core_id 6:
isolated : false
port: dpdkphy0 queue-id: 0 pmd usage: 64 %
port: dpdkvhost1 queue-id: 0 pmd usage: 0 %
These values are what would be used as part of rxq to pmd
assignment due to a reconfiguration event e.g. adding pmds,
adding rxqs or with the command:
ovs-appctl dpif-netdev/pmd-rxq-rebalance
