[PATCH v3 1/2] app/testpmd: do not poll stopped queues

[Dmitry Kozlyuk]

> Calling Rx/Tx functions on a stopped queue is not supported.
> Do not run packet forwarding for streams that use stopped queues.
> 
> Each stream has a read-only "disabled" field,
> so that lcore function can skip such streams.
> Forwarding engines can set this field
> using a new "stream_init" callback function
> by checking relevant queue states,
> which are stored along with queue configurations
> (not all PMDs implement rte_eth_rx/tx_queue_info_get()
> to query the state from there).
> 
> Fixes: 5f4ec54f1d16 ("testpmd: queue start and stop")

The sibling ethdev patch will have to wait until the next release cycle.
