Linux kernel source tree
927441adea
The mv88e6xxx_port_setup_mac checks if the requested MAC settings are different from the current ones, and if not, does nothing (since chaning them requires putting the link down). In this check it only looks if the triplet [link, speed, duplex] is being changed. This patch adds support to also check if the mode parameter (of type phy_interface_t) is requested to be changed. The current mode is computed by the ->port_link_state() method, and if it is different from PHY_INTERFACE_MODE_NA, we check for equality with the requested mode. In the implementations of the mv88e6250_port_link_state() method we set the current mode to PHY_INTERFACE_MODE_NA - so the code does not check for mode change on 6250. In the mv88e6352_port_link_state() method, we use the cached cmode of the port to determine the mode as phy_interface_t (and if it is not enough, eg. for RGMII, we also look at the port control register for RX/TX timings).

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.
