Linux kernel modifications for the Kernel Hacking exam

For DSA switches that do not have an .adjust_link callback, aka those who transitioned totally to the PHYLINK-compliant API, use PHYLINK to drive the CPU/DSA ports. The PHYLIB usage and .adjust_link are kept but deprecated, and users are asked to transition from it. The reason why we can't do anything for them is because PHYLINK does not wrap the fixed-link state behind a phydev object, so we cannot wrap .phylink_mac_config into .adjust_link unless we fabricate a phy_device structure. For these ports, the newly introduced PHYLINK_DEV operation type is used and the dsa_switch device structure is passed to PHYLINK for printing purposes. The handling of the PHYLINK_NETDEV and PHYLINK_DEV PHYLINK instances is common from the perspective of the driver.

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.
