Subject: [PATCH v6 07/46] virtio: add virtio 1.0 feature bit
Date: Thu, 27 Nov 2014 22:08:14 +0200	[thread overview]
Message-ID: <1417118789-18231-8-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1417118789-18231-1-git-send-email-mst@redhat.com>

Based on original patches by Rusty Russell, Thomas Huth
and Cornelia Huck.

Note: at this time, we do not negotiate this feature bit
in core, drivers have to declare VERSION_1 support explicitly.

For this reason we treat this bit as a device bit
and not as a transport bit for now.

After all drivers are converted, we will be able to
move VERSION_1 to core and drop it from all drivers.
