Subject: [dpdk-dev] [PATCH v2 8/9] app/eventdev: switch sequence number to dynamic mbuf field
Date: Wed, 28 Oct 2020 13:20:12 +0100
Message-ID: <20201028122013.31104-9-david.marchand@redhat.com> (raw)
In-Reply-To: <20201028122013.31104-1-david.marchand@redhat.com>

The order test stored a sequence number in the deprecated mbuf field
seqn.
It is moved to a dynamic field in order to allow removal of seqn.

Signed-off-by: David Marchand <david.marchand@redhat.com>
