Pull up following revision(s) (requested by jakllsch in ticket #48):
sys/dev/pci/virtio.c: revision 1.64
sys/dev/pci/virtio.c: revision 1.65
Fix dmamap_syncs more; the number of ring elements is vq->vq_num, not
sc->sc_nvqs.
Subtly adjust criteria for notification of Virtio devices in
VIRTIO_F_RING_EVENT_IDX mode.
This fixes stalls in the vioif(4) transmit path that would happen sooner
or later, depending on interface transmit utilization, and were
particularly noticable with a NetBSD guest transmitting to its x86 KVM
host at multi-gigabit speeds.
