Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2047636 commit d43c65b05b848e0b2db1a6c78b02c189da3a95b5 Author: Heiner Kallweit <hkallweit1@gmail.com> Date: Sun Aug 1 12:41:31 2021 +0200 ethtool: runtime-resume netdev parent in ethnl_ops_begin If a network device is runtime-suspended then: - network device may be flagged as detached and all ethtool ops (even if not accessing the device) will fail because netif_device_present() returns false - ethtool ops may fail because device is not accessible (e.g. because being in D3 in case of a PCI device) It may not be desirable that userspace can't use even simple ethtool ops that not access the device if interface or link is down. To be more friendly to userspace let's ensure that device is runtime-resumed when executing the respective ethtool op in kernel.

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.
