Subject: [dpdk-dev] [PATCH 5/7] net/virtio: check protocol feature in user backend
Date: Fri, 11 Sep 2020 17:08:03 +0200	[thread overview]
Message-ID: <20200911150805.79901-6-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20200911150805.79901-1-maxime.coquelin@redhat.com>

When sending set status message, move protocol feature check
to vhost_user to be compatible with different backend types.
