Modified Files: src/sys/dev/pci: virtio.c Log Message: 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.
