patch 'test/bonding: fix active backup receive test' has been queued to stable release 24.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/17/25. 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/8ed4c26a454c42d24c0dcb27d8d7983f5237432a

Thanks.

Kevin

Subject: [PATCH] test/bonding: fix active backup receive test

[ upstream commit eb29e625ce41b50898efc8e2618b7eeb128460ed ]

The test had incorrect assumptions about how active backup
should work. When in active backup mode, the secondary (not primary)
ports should be ignored. The test was always broken since initially
written but earlier bug was masking the part of the test which
tested non-primary ports.

Bugzilla ID: 1589
Fixes: 112ce3917674 ("test/bonding: fix loop on members")
