Vmxnet3 version 3 device supports checksum/TSO offload. Thus, vNIC to pNIC traffic can leverage hardware checksum/TSO offloads. However, vmxnet3 does not support checksum/TSO offload for Geneve/VXLAN encapsulated packets. Thus, for a vNIC configured with an overlay, the guest stack must first segment the inner packet, compute the inner checksum for each segment and encapsulate each segment before transmitting the packet via the vNIC. This results in significant performance penalty. This patch will enhance vmxnet3 to support Geneve/VXLAN TSO as well as checksum offload.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
