>Subject: [PATCH v2 25/38] ppc: qemu: Enable VirtIO NET support
>
>By default the QEMU ppce500 machine connects a VirtIO NET to the PCI
>controller, although it can be replaced to an e1000 NIC via additional command
>line options.
>
>Now that we have switched over to DM PCI, VirtIO support becomes possible.
>This commit enables the support.
