Subject: [PATCH RFC v2 11/12] virtio-net/virtio-blk: enable virtio 1.0
Date: Tue, 25 Nov 2014 14:24:22 +0100	[thread overview]
Message-ID: <1416921863-16523-12-git-send-email-cornelia.huck@de.ibm.com> (raw)
In-Reply-To: <1416921863-16523-1-git-send-email-cornelia.huck@de.ibm.com>

virtio-net (non-vhost) and virtio-blk have everything in place to support
virtio 1.0: let's enable the feature bit for them.

Note that VIRTIO_F_VERSION_1 is technically a transport feature; once
every device is ready for virtio 1.0, we can move this setting this
feature bit out of the individual devices.
