Subject: [PATCH v2] test/bonding: fix active backup rx test
Date: Fri, 13 Dec 2024 09:17:14 -0800	[thread overview]
Message-ID: <20241213171713.13266-2-stephen@networkplumber.org> (raw)
In-Reply-To: <20241213015158.10174-1-stephen@networkplumber.org>

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")
Cc: stable@dpdk.org
