Yangbo Lu says: ==================== Support Ocelot PTP Sync one-step timestamping This patch-set is to support Ocelot PTP Sync one-step timestamping. Actually before that, this patch-set cleans up and optimizes the DSA slave tx timestamp request handling process. Changes for v2: - Split tx timestamp optimization patch. - Updated doc patch. - Freed skb->cb usage in dsa core driver, and moved to device drivers. - Other minor fixes. Changes for v3: - Switched sequence of patch #3 and #4 with rebasing to fix build. - Replaced hard coded 48 of memset(skb->cb, 0, 48) with sizeof(). ==================== 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.
