patch 'net/intel: prevent selection of a null Rx burst function' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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/d026945e38f800912359d0724532f040f545b5e8

Thanks.

Kevin

Subject: [PATCH] net/intel: prevent selection of a null Rx burst function

[ upstream commit 2e97d51b5572a58de348cf3524012aa7391c70bf ]

Depending on the underlying architecture and CPU flags available, a
different set of Rx paths may be defined by a driver using the common
path selection infrastructure. However the Rx path selection function
iterates through the entire array of potential Rx paths, regardless of
whether they are available for selection by that platform. This could
result in a null Rx burst function being selected. Fix this by
discarding paths with a null Rx burst function from selection.

Fixes: 9d99641d80a0 ("net/intel: introduce infrastructure for Rx path selection")
