The 8000 series and newer NICs all get hardware timestamps from the MAC and can provide timestamps on a normal TX queue, rather than via a slow path through the MC. As such we can use this path for any packet where a hardware timestamp is requested. This also enables support for PTP over transports other than IPv4+UDP.

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.
