Subject: [dpdk-dev] [PATCH v3 5/8] net/virtio: check protocol feature in user backend
Date: Tue, 29 Sep 2020 18:14:01 +0200 [thread overview]
Message-ID: <20200929161404.124580-6-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20200929161404.124580-1-maxime.coquelin@redhat.com>
When sending set status message, move protocol feature check
to vhost_user to be compatible with different backend types.
