    Receive side scaling (RSS) and multiqueue support are included in the VMXNET3 Linux device driver. The VMXNET3 device always supported multiple queues, but the Linux driver used just one Rx and one Tx queue previously.

    For the VMXNET3 driver shipped with VMware Tools, multiqueue support was introduced in vSphere 5.0.
    For the VMXNET3 driver included with the Linux operating system, multiqueue support was introduced after and including Linux kernel version 2.6.37.
