Subject: [dpdk-stable] [PATCH v2 3/3] virtio-user: set status on virtio-user reconnect
Date: Tue, 20 Oct 2020 17:20:52 +0200
Message-ID: <20201020152052.389446-4-amorenoz@redhat.com> (raw)
In-Reply-To: <20201020152052.389446-1-amorenoz@redhat.com>

Newer vhost-user backends will rely on SET_STATUS to start the device
so this required to support them.
