When receiving a packet over the virtio network channel, translate the virtio flag VIRTIO_NET_HDR_F_NEEDS_CSUM not to CSUM_DATA_VALID | CSUM_PSEUDO_HDR, but to CSUM_TCP, CSUM_TCP_IPV6, CSUM_UDP, or CSUM_UDP_IPV6. The second change fixes a series of issue related to checksum offloading for if_vtnet. While there, improve the stats counters to allow a detailed view on what is going on in relation to checksum offloading.
