When operating in fixed phy mode and if there is repeated open/close
phy test cases, everytime the fixed phy is registered as a new phy
which leads to overrun after 32 iterations. It is solved by adding
fixed_phy_unregister() in the phy_close path.
In phy_close path, netdev->phydev cannot be used directly in
fixed_phy_unregister() due to two reasons,
- netdev->phydev is set to NULL in phy_disconnect()
- fixed_phy_unregister() can be called only after phy_disconnect()
So saving the netdev->phydev in local variable 'phydev' and
passing it to phy_disconnect().

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.
