Add a separate set of PCS operations, which MAC drivers can use to couple phylink with their associated MAC PCS layer. The PCS operations include: - pcs_get_state() - reads the link up/down, resolved speed, duplex and pause from the PCS. - pcs_config() - configures the PCS for the specified mode, PHY interface type, and setting the advertisement. - pcs_an_restart() - restarts 802.3 in-band negotiation with the link partner - pcs_link_up() - informs the PCS that link has come up, and the parameters of the link. Link parameters are used to program the PCS for fixed speed and non-inband modes.

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.
