Subject: [dpdk-dev] [PATCH 5/8] dpaa: switch sequence number to dynamic field
Date: Tue, 27 Oct 2020 23:13:40 +0100 [thread overview]
Message-ID: <20201027221343.28551-6-david.marchand@redhat.com> (raw)
In-Reply-To: <20201027221343.28551-1-david.marchand@redhat.com>
The dpaa drivers have been hacking the deprecated field seqn for
internal features.
It is moved to a dynamic mbuf field in order to allow removal of seqn.
Signed-off-by: David Marchand <david.marchand@redhat.com>
