This issue is caused by an update for the vmxnet3 driver that addressed RSS features added in NDIS version 6.30 rendering the functionality unusable. If the RSS feature is turned on, the Windows Receive Side Scaling (RSS) feature is not functional on virtual machines running these versions of VMware Tools using VMXNET3 network adapters. VMware has confirmed there is an incompatibility between VMware Tools versions 9.10.0 (vSphere 6.0) through 10.1.5 (vSphere 6.0p05) and the RSS feature available in Microsoft Windows 2008 or later. For more information on Network Adapters, see Introduction to Cloud Server NICs in MCP 2.0. However, users can turn on this function and potentially run into the issue described below. By default, this function is disabled when using the VMXNET3 network adapter on a NIC. Receive Side Scaling (RSS) is a Microsoft function that provides increased network performance on multiprocessor environments in Microsoft Windows 2008 and later.
