This switch family can have up to 8 UTP ports {0..7}. However,
INDIRECT_ACCESS_ADDRESS_PHYNUM_MASK was using 2 bits instead of 3,
dropping the most significant bit during indirect register reads and
writes. Reading or writing ports 4, 5, 6, and 7 registers was actually
manipulating, respectively, ports 0, 1, 2, and 3 registers.
This is not sufficient but necessary to support any variant with more
than 4 UTP ports, like RTL8367S.
rtl8365mb_phy_{read,write} will now returns -EINVAL if phy is greater
than 7.
Fixes: 4af2950c50 ("net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VC")

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.
