vmxnet9

Usage

Overview

This is a Linux kernel device driver module that drives VMware's fast networking device. As it is backed by real (virtual) hardware, it should be automatically loaded by hotplug or udev as needed. For best performance, it is recommended to enable TSO on all interfaces driven by vmxnet using ethtool.

The shell code to do this might look like this:

if which ethtool >/dev/null 2>&1; then
for ethif in `ifconfig -a | grep ^eth | cut -d' ' -f1`; do
ethtool -K $ethif tso on >/dev/null 2>&1
done fi

The VMware backend may present the fast networking device as an AMD vlance device instead of the actual vmxnet device.
