Russell King says: ==================== net: dsa: microchip: use phylink_mac_ops for ksz driver This four patch series switches the Microchip KSZ DSA driver to use phylink_mac_ops support, and for this one we go a little further beyond a simple conversion. This driver has four distinct cases: lan937x ksz9477 ksz8 ksz8830 Three of these cases are handled by shimming the existing DSA calls through ksz_dev_ops, and the final case is handled through a conditional in ksz_phylink_mac_config(). These can all be handled with separate phylink_mac_ops. To get there, we do a progressive conversion. Patch 1 removes ksz_dev_ops' phylink_mac_config() method which is not populated in any of the arrays - and is thus redundant. Patch 2 switches the driver to use a common set of phylink_mac_ops for all cases, doing the simple conversion to avoid the DSA shim. Patch 3 pushes the phylink_mac_ops down to the first three classes (lan937x, ksz9477, ksz8) adding an appropriate pointer to the phylink_mac_ops to struct ksz_chip_data, and using that to populate DSA's ds->phylink_mac_ops pointer. The difference between each of these are the mac_link_up() method. mac_config() and mac_link_down() remain common between each at this stage. Patch 4 splits out ksz8830, which needs different mac_config() handling, and thus means we have a difference in mac_config() methods between the now four phylink_mac_ops structures. Build tested only, with additional -Wunused-const-variable flag. ==================== Link: https://lore.kernel.org/r/ZivP/R1IwKEPb5T6@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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 reStructuredText 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.
