[Qemu-devel] [PATCH] virtio-net: fix macaddr config regression

[Mark McLoughlin <markmc@redhat.com>]

This commit:

    commit 97b15621
    virtio: use qdev properties for configuration.

    Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

makes a guest using virtio-net see an empty macaddr because we never
copy the macaddr into the location that virtio_net_get_config() uses.
