Modifying the link settings via phylink_ethtool_ksettings_set() and phylink_ethtool_set_pauseparam() didn't always work as intended for PHY based setups, as calling phylink_mac_config() would result in the unresolved configuration being committed to the MAC, rather than the configuration with the speed and duplex setting. This would work fine if the update caused the link to renegotiate, but if no settings have changed, phylib won't trigger a renegotiation cycle, and the MAC will be left incorrectly configured. Avoid calling phylink_mac_config() unless we are using an inband mode in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as introduced in 4.20 to set the PHY settings in phylink_ethtool_set_pauseparam().

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.
