In virtio-0.9.5, the size of the virtio-net packet header depends on whether the VIRTIO_NET_F_MRG_RXBUF feature is negotiated -- the "num_buffers" field is only appended to the header if the feature is negotiated. Since we never negotiate this feature, VirtioNetDxe never allocates room for the "num_buffers" field. With virtio-1.0, the "num_buffers" field is always there (although it doesn't carry useful information without VIRTIO_NET_F_MRG_RXBUF). Adapt the buffers that depend on the virtio-net header size (otherwise we have skewed / truncated packets).
