.Dd August 4, 2013 .Dt VMX 4 .Os .Sh NAME .Nm vmx .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: d -ragged -offset indent .Cd "device vmx" .Ed

p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -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.

p This driver supports the c 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.

p The .Nm driver supports VMXNET3 VMware virtual NICs provided by the virtual machine hardware version 7 or newer, as provided by the following products:

p l -bullet -compact -offset indent t VMware ESX/ESXi 4.0 and newer t VMware Server 2.0 and newer t VMware Workstation 6.5 and newer t VMware Fusion 2.0 and newer .El

p 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: d -literal -offset indent ethernet0.virtualDev = "vmxnet3" .Ed .Sh SEE ALSO .Xr altq 4 , .Xr arp 4 , .Xr em 4 , .Xr netintro 4 , .Xr ng_ether 4 , .Xr pcn 4 , .Xr vlan 4 , .Xr ifconfig 8 .Sh AUTHORS .An -nosplit The .Nm driver was ported from .Ox by .An Bryan Venteicher Aq bryanv@freebsd.org . The .Ox driver was written by .An Tsubai Masanari .
