The ksz_switch_chips[] element for KSZ9477 says that port 5 is an xMII port and it supports speeds of 10/100/1000. The device tree example does declare a fixed-link at 1000, and RGMII is the only one of those modes that supports this speed, so use this phy-mode. The microchip,ksz8565 compatible string is not supported by the microchip driver, however on Microchip's product page it says that there are 5 ports, 4 of which have internal PHYs and the 5th is an MII/RMII/RGMII port. It's a bit strange that this is port@6, but it is probably just the way it is. Select an RGMII phy-mode for this one as well.

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.
