patch 'ethdev: add internal function to device struct from name' 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 02/26/22. 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/721d0bbd1668d2a4b617a4a4de0b93dd60283d58

Thanks.

Kevin

Subject: [PATCH] ethdev: add internal function to device struct from name

[ upstream commit 961fb4029b8c52c0e8230d34993c354d70e10e14 ]

The PMDs would need a function to access the rte_eth_devices
without accessing the global rte_eth_device array.
