As some IP variants switch to reset mode (and thus the register contents is lost) when setting clocks (due to module standby functionality) to be able to implement runtime PM and save more power, set the IP's operating mode to reset at the end of the probe. Along with it, in the ndo_open API the IP will be switched to configuration, then operation mode. In the ndo_close API, the IP will be switched back to reset mode. This allows implementing runtime PM and, along with it, save more power when the IP is not 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 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.
