[dpdk-dev] 18.08 Intel Roadmap

[Rosen, Rami]

Hi, Tim,
Thanks for posting the planned 18.08 roadmap, I hope other 
vendors will follow!

>Allow Setup/Reconfiguration/Tear Down of Queues at Run Time - >Currently, to configure a DPDK ethdev, the application specifies how >many Tx and Rx queues to include prior to starting the device. This >feature introduces a more dynamic approach where the application can >also setup/reconfigure/tear down queues after the device has been >started (on NICs where this is supported in hardware).

Maybe I am wrong, but isn't this already included in DPDK 18.05  ? 

In DPDK 18.05 release notes: 
https://dpdk.org/doc/guides/rel_notes/release_18_05.html

We have the following section:
...
ethdev: Runtime queue setup

rte_eth_rx_queue_setup and rte_eth_tx_queue_setup can be called after rte_eth_dev_start if the device supports runtime queue setup. The device driver can expose this capability through rte_eth_dev_info_get. A Rx or Tx queue set up at runtime need to be started explicitly by rte_eth_dev_rx_queue_start or rte_eth_dev_tx_queue_start.
...

And there is the following patchset from Qi, from April, adding support for runtime queue setup (in I40E and in the librte_ether library, which 
was renamed to librte_ethdev in the meanwhile):
