.Nd VMware VMXNET3 Virtual Interface Controller device
|
||||
.Sh SYNOPSIS
|
||||
To compile this driver into the kernel,
|
||||
place the following line in your
|
||||
kernel configuration file:
|
||||
.Bd -ragged -offset indent
|
||||
.Cd "device vmx"
|
||||
.Ed
|
||||
.Pp
|
||||
Alternatively, to load the driver as a
|
||||
module at boot time, place the following line in
|
||||
.Xr loader.conf 5 :
|
||||
.Bd -literal -offset indent
|
||||
if_vmx_load="YES"
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for the VMXNET3 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 VMXNET3
|
||||
driver protocol, as an alternative to the emulated
|
||||
.Xr pcn 4 ,
|
||||
.Xr em 4
|
||||
interfaces also available in the VMware environment.
|
||||
The
|
||||
.Nm
|
||||
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.
|
||||
The
|
||||
.Nm
|
||||
driver supports features like multiqueue support, IPv6
|
||||
checksum offloading, MSI/MSI-X support and hardware VLAN tagging in
|
||||
VMware's VLAN Guest Tagging (VGT) mode.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
driver supports VMXNET3 VMware virtual NICs provided by the virtual
|
||||
machine hardware version 7 or newer, as provided by the following
|
||||

||||
