[Qemu-devel] [PATCH v3 4/7] virtio-net-s390: switch to the new API.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

Here the virtio-net-s390 is modified for the new API. The device
virtio-net-s390 extends virtio-s390-device as before. It creates and
connects a virtio-net-device during the init. The properties are not modified.
