devnp-vmxnet3.so

Driver for the VMware VMXNET3 network interface

Syntax:

io-pkt-variant -d vmxnet3 ...

where variant is v4-hc or v6-hc.

Runs on:

QNX Neutrino

Targets:

x86_64

Options:

None.

Description:

The devnp-vmxnet3.so 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:

  • ip4csum-rx
  • tcp4csum, tcp4csum-rx, tcp4csum-tx
  • tcp6csum, tcp6csum-rx, tcp6csum-tx
  • tso4, tso6
  • udp4csum, udp4csum-rx, udp4csum-tx
  • udp6csum, udp6csum-rx, udp6csum-tx

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.

Examples:

Start the v6 TCP/IP variant of io-pkt using the devnp-vmxnet3.so driver: 

io-pkt-v6-hc -dvmxnet3 verbose
if_up -p vx0
ifconfig sc0 192.0.2.1
