In particular, the virtio header always has the u16 num_buffers field. We define a new 'struct virtio_net_hdr_v1' for this (rather than simply calling it 'struct virtio_net_hdr', to avoid nasty type errors if some parts of a project define VIRTIO_NET_NO_LEGACY and some don't. Transitional devices (which can't define VIRTIO_NET_NO_LEGACY) will have to keep using struct virtio_net_hdr_mrg_rxbuf, which has the same byte layout as struct virtio_net_hdr_v1.
