Currently, Tx completions are reported using Completion Queue Element version 1 (CQEv1). These elements do not contain the Tx time stamp, which is fine as Spectrum-1 reads Tx time stamps via a dedicated FIFO and Spectrum-2 does not currently support PTP. In preparation for Spectrum-2 PTP support, use CQEv2 for Spectrum-2 and newer ASICs, as this CQE format encodes the Tx time stamp.

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.
