Subject: [PATCH v3 02/17] test/bbdev: extend HARQ tolerance
Date: Thu,  2 Mar 2023 12:21:56 -0800	[thread overview]
Message-ID: <20230302202211.170017-3-hernan.vargas@intel.com> (raw)
In-Reply-To: <20230302202211.170017-1-hernan.vargas@intel.com>

HARQ memory implementation could have different size assumptions.
Extending HARQ tolerance to cover different implementations.

Fixes: 335c11fd276 ("app/bbdev: support HARQ validation")
