Environment

VMware vSphere ESXi 6.0

Resolution

Summaries and Symptoms

This patch updates the net-vmxnet3 VIB to resolve an issue where decreased traffic throughput is observed in a Red Hat Enterprise Linux (RHEL) VM that uses e1000 network adapter in an nested ESXi environment that has VMXNET3 as the adapter.

The issue is resolved by disabling Large Receive Offload (LRO) for VMXNET3 VMkernel driver by default.

Note: To enable LRO, run the following command and reboot:

esxcli system module parameters set -m vmxnet3 -p disable_lro=0

Patch Download and Installation

The typical way to apply patches to ESXi hosts is through the VMware vSphere Update Manager. For details, see the Installing and Administering VMware vSphere Update Manager.
ESXi hosts can be updated by manually downloading the patch ZIP file from the VMware download page and installing the VIB by using the esxcli software vib command. Additionally, the system can be updated using the image profile and the esxcli software profile command. For details, see the vSphere Command-Line Interface Concepts and Examples and the vSphere Upgrade Guide.
