Mark TX timestamp type per skb on skb->cb[0], instead of global variable for all skbs. This is a preparation for one step timestamp support. For one-step timestamping enablement, there will be both one-step and two-step PTP messages to transfer. And a skb queue is needed for one-step PTP messages making sure start to send current message only after the last one completed on hardware. (ENETC single-step register has to be dynamically configured per message.) So, marking TX timestamp type per skb is required.

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.
