— VMware
VMXNET3 Virtual Interface Controller device
vmx* at pci? dev ? function ?
The vmx
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.
This driver supports the VMXNET3
driver
protocol, as an alternative to the emulated
pcn(4),
wm(4) interfaces also available in
the VMware environment. The vmx
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. In comparison to the earlier VMXNET versions,
VMXNET3 supports additional features like multiqueue support, IPv6 checksum
offloading, MSI/MSI-X support and hardware VLAN tagging in VMware's VLAN
Guest Tagging (VGT) mode.
The vmx
driver supports VMXNET3 VMware
virtual NICs provided by the virtual machine hardware version 7 or newer, as
provided by the following products:
The vmx
driver supports the following
media types:
For more information on configuring this device, see ifconfig(8).
The following entry must be added to the VMware configuration file
to provide the vmx
device:
ethernet0.virtualDev = "vmxnet3"
arp(4), ifmedia(4), intro(4), netintro(4), pci(4), pcn(4), wm(4), ifconfig(8)
The vmx
device driver first appeared in
OpenBSD 5.5 and was ported for
NetBSD 7.0.
The vmx
driver was originally written by
Tsubai Masanari. NetBSD
porting was done by Hikaru ABE
