[Qemu-devel] [PATCH] Adds virtio_net as the default netcard for boston board

[Tommy Jin]

Boston didn't bring up any netcard by default, this is not so convenient.
As the linux kernel has supported virtio_net, now add a virtio netcard for 
boston.
To make virtio work properly, please:
1. set virtio net options in linux kernel, saying CONFIG_VIRTIO && 
CONFIG_VIRTIO_PCI && CONFIG_VIRTIO_NET
2. specify model=virtio when you start netcard in qemu.
