NAME
vio —
VirtIO network device
SYNOPSIS
vio* at virtio? flags 0x00
DESCRIPTION
The vio driver provides support for the
virtio(4) network interface provided by bhyve, KVM, QEMU, and
VirtualBox.
Setting flags to 0x02 disables the RingEventIndex feature. This
can be tried as a workaround for possible bugs in host implementations or
vio at the cost of slightly reduced performance.
