The KSZ8795 switch has 4 external ports {0,1,2,3} and 1 CPU port {4}, so does the KSZ8765. The KSZ8794 seems to be repackaged KSZ8795 with different ID and port 3 not routed out, however the port 3 registers are present in the silicon, so the KSZ8794 switch has 3 external ports {0,1,2} and 1 CPU port {4}. Currently the driver always uses the last port as CPU port, on KSZ8795/KSZ8765 that is port 4 and that is OK, but on KSZ8794 that is port 3 and that is not OK, as it must also be port 4. This patch adjusts the driver such that it always registers a switch with 5 ports total (4 external ports, 1 CPU port), always sets the CPU port to switch port 4, and then configures the external port mask according to the switch model -- 3 ports for KSZ8794 and 4 for KSZ8795/KSZ8765.

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.
