Subject: [PATCH v2 3/3] app/testeventdev: fix timestamp with crypto producer
Date: Fri, 4 Nov 2022 13:25:56 +0100 [thread overview]
Message-ID: <20221104122556.751286-4-vfialko@marvell.com> (raw)
In-Reply-To: <20221104122556.751286-1-vfialko@marvell.com>
With symmetric crypto producer and enabled `--fwd_latency` we will
treat rte_mbuf as perf_elt which will lead to rte_mbuf header
corruption. Use rte_mbuf data to store time stamp information.
For asymmetric add space in result data for time stamp.
Fixes: de2bc16e1bd1 ("app/eventdev: add crypto producer mode")
Cc: stable@dpdk.org
