Russell King says: ==================== net: dsa: mv88e6xxx: get rid of SPEED_MAX This series does two things: 1. it gets rid of mv88e6065_port_set_speed_duplex() which is completely unused (do we support this device? I couldn't find it in the tables in chip.c) This has a max speed of 200Mbps which we don't support. 2. get rid of the SPEED_MAX constant, which is used to configure a DSA or CPU port to their maximum speed during initialisation. We no longer need this as we can derive the maximum port speed from the mac_capabilities instead. The reason for making this change is in preparation for phylink to be used by DSA for CPU ports. This omission has come back to bite us with the conversion of DSA drivers to phylink_pcs, since phylink_pcs won't get used unless phylink is being used. Particularly with this driver, it is very common for DT descriptions to omit the fixed-link details which means "use maximum speed". It will eventually be necessary to hoist the selection of "max speed" into the DSA layer (trivial) and also have a way for the DSA driver to tell the DSA layer which interface it should be using for these ports. ==================== Link: https://lore.kernel.org/r/YrGQBssOvQBZiDS4@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 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.
