Driver for the VMware VMXNET3 network interface


io-pkt-variant -d vmxnet3 ... 

where variant is v4-hc or v6-hc.

Runs on:

QNX Neutrino






The driver supports the VMXNET3 network interface supported by VMware. Its interface names are in the form vxX, where X is an integer.

Some devices support hardware checksums, although some might do so in only one direction; to determine if your device does, type:

ifconfig vxX

and look for the following in the list of supported options:

You can then use ifconfig to enable or disable whichever of these options your device supports.

Note: The network drivers don't put entries into the /dev namespace, so a waitfor command for such an entry won't work properly in buildfiles or scripts. Use if_up -p instead; for example, if_up -p vx0.


Start the v6 TCP/IP variant of io-pkt using the driver:

io-pkt-v6-hc -dvmxnet3 verbose
if_up -p vx0
ifconfig sc0
