patch 'doc: improve configuration examples in idxd guide' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/06/22. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/9970eab8c427905c6189ea4e1de0b56395fdc855

Thanks.

Kevin

Subject: [PATCH] doc: improve configuration examples in idxd guide

[ upstream commit 7a8a886f38a5a6dfc0bc42fe46ae1feb45d805b8 ]

The documentation on how to configure device instances using
accel-config can be improved by a number of changes:

* For initial example, when only configuring one queue, omit
  configuration of a second engine, which is unused later.
* Add the "max-batch-size" setting to the options being configured for
  each queue
* Add a final, more complete example, showing configuration of multiple
  queues on a device.
