The Windows Receive Side Scaling (RSS) feature is not functional on virtual machines running VMware Tools versions 9.10.0 up to 10.1.5.VMware is aware of the following reported issues affecting Windows Server 2012 / 2012R2 and newer Guest Operating Systems on VMware vSphere: It is observed in VMXNET3 driver versions from 1.6.6.0 to 1.7.3.0.
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. Receive Side Scaling is not functional for vmxnet3 on Windows 8 and Windows 2012 Server or later. We thank you very much for your patience and understanding while we worked on fixing this problem. Please download and install this version of the VMware Tools, especially if you are using the VMXNet3 vNIC type for your Windows VMs. We have just released a new version of the VMware Tools which fixes the issue described in this post (below). Recommended drivers versions for Windows and Microsoft Business Critical applications is: 1.7.3.7 Please download and update your VMware Tools, even if only for the additional improvements in VMXNet3 vNIC drivers.
We have released VMware Tools Version 10.2.0, with more fixes and improvements for VMXNet3 vNICs.
