The short answer is no. Pktgen binds lcores to ports for TX or RX and if you bind one lcore to a port then it will only send to queue id zero for that port. If you bind more then one lcore to a port Rx or TX then it will send on all queues (O - N) as Pktgen does not allow control of a specific lcore/queue.
