This patch adds support for initializing the MACsec engine found within some Microsemi PHYs. The engine is initialized in a passthrough mode and does not modify any incoming or outgoing packet. But thanks to this it now can be configured to perform MACsec transformations on packets, which will be supported by a future patch. The MACsec read and write functions are wrapped into two versions: one called during the init phase, and the other one later on. This is because the init functions in the Microsemi PHY driver are called while the MDIO bus lock is taken. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.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.
