Subject: [PATCH] virtio-spec: tweak wording for console control vq
Date: Mon, 20 May 2013 15:20:52 +0300	[thread overview]
Message-ID: <20130520122051.GA11581@redhat.com> (raw)

control vq is only used if feature bit is
negotiated - it's not enough that device supports
it. Clarify this in the spec.
