TX Timestamp in XGMAC comes from MAC instead of descriptors. Implement this in a new callback. Also, RX Timestamp in XGMAC must be cheked against corruption and we need a barrier to make sure that descriptor fields are read correctly. Changes from v2: - Rework return code check (Jakub) Changes from v1: - Rework the get timestamp function (David) Signed-off-by: Jose Abreu <joabreu@synopsys.com> Signed-off-by: David S.

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.
