This patch enhances vmxnet3 to support latency measurement. This support will help to track the latency in packet processing between guest virtual nic driver and host. For this purpose, we introduce a new timestamp ring in vmxnet3 which will be per Tx/Rx queue. This ring will be used to carry timestamp of the packets which will be used to calculate the latency. User can enable latency measurement using realtime knob in vnic setting in VCenter.

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 reStructuredText 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.
