.Sh NAME
.Nm vic
.Nd VMware VMXnet Virtual Interface Controller device
.Sh SYNOPSIS
.Cd vic* at pci?
.Sh DESCRIPTION
The
.Nm
driver provides support for the VMXnet virtual NIC available in virtual
machines by VMware.
It appears as a simple Ethernet device but is actually a virtual network
interface to the underlying host operating system.
.Pp
This driver supports the
.Ic vmxnet
driver protocol, as an alternative to the emulated
.Xr pcn 4
and
.Xr em 4
interfaces also available in the VMware environment.
The
.Nm vic
driver is optimized for the virtual machine, it can provide advanced
capabilities depending on the underlying host operating system and
the physical network interface controller of the host.
.Pp
The
.Nm
driver supports VMware virtual NICs provided by the following products:
.Pp
.Bl -bullet -compact -offset indent
.It
VMware ESX 2.0 and newer
.It
VMware GSX 2.5 and newer
.It
VMware Server 1.0 and newer
.It
VMware Workstation 4.5 and newer
.It

The
.Nm
driver supports the following media types:
.Bl -tag -width autoselect
.It autoselect
Enable autoselection of the media type and options.
The driver always uses the fastest available speed and the media
options provided by the underlying host of the virtual machine.

.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh EXAMPLES
The following entry must be added to the VMware configuration file
to provide the
.Nm
device:
.Bd -literal -offset indent
ethernet0.virtualDev = "vmxnet"

.Sh BUGS
There are tons of bugs in VMware and the underlying host operating systems.
Please consider that the security of the
.Ox
guest can be circumvented by attacking the host environment.
