Some ethernet drivers may call phy_start() and phy_stop() from ndo_open() and ndo_close() respectively. When network cable is unconnected, and operate like below: step 1: ifconfig ethX up -> ndo_open -> phy_start ->start autoneg, and phy is no link. step 2: ifconfig ethX down -> ndo_close -> phy_stop -> just stop phy state machine. This patch forces phy suspend even phydev->link is off. Signed-off-by: Jian Shen <shenjian15@huawei.com> Reviewed-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

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.
