With the addition of more link speed mode to the netdev trigger, it was pointed out that there may be a problem with bloating the attribute list with modes that won't ever be supported by the trigger as the attached device name doesn't support them. To clear and address this problem, change the logic where these additional trigger modes are listed. Since the netdev trigger REQUIRE a device name to be set, attach to the device name change function additional logic to parse the supported link speed modes using ethtool APIs and show only the supported link speed modes attribute. Link speed attribute are refreshed on device_name set and on NETDEV_CHANGE events. This only apply to the link speed modes and every other mode is still provided by default.

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.
