Subject: [PATCH v8 27/50] virtio_net: disable mac write for virtio 1.0
Date: Mon, 1 Dec 2014 18:05:00 +0200 [thread overview]
Message-ID: <1417449619-24896-28-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1417449619-24896-1-git-send-email-mst@redhat.com>
The spec states that mac in config space is only driver-writable in the
legacy case. Fence writing it in virtnet_set_mac_address() in the
virtio 1.0 case.
Suggested-by: Cornelia Huck <cornelia.huck@de.ibm.com>
