Linux kernel source tree
16e6592cd5
DSA initalises the ds->num_ports amount of ports in
dsa_switch_touch_ports(). When the PHY muxing feature is in use, port 5
won't be defined in the device tree. Because of this, the type member of
the dsa_port structure for this port will be assigned DSA_PORT_TYPE_UNUSED.
The dsa_port_setup() function calls ds->ops->port_disable() when the port
type is DSA_PORT_TYPE_UNUSED.
The MT7530_P5_DIS bit is unset in mt7530_setup() when PHY muxing is being
used. mt7530_port_disable() which is assigned to ds->ops->port_disable() is
called afterwards. Currently, mt7530_port_disable() sets MT7530_P5_DIS
which breaks network connectivity when PHY muxing is being used.
Therefore, do not set MT7530_P5_DIS when PHY muxing is being used.

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.
