[ Upstream commit3af409ca27] The following call path suggests that calling unregister_netdev on an interface that is up will first bring it down. enetc_pf_remove -> unregister_netdev -> unregister_netdevice_queue -> unregister_netdevice_many -> dev_close_many -> __dev_close_many -> enetc_close -> enetc_stop -> phylink_stop However, enetc first destroys the phylink instance, then calls unregister_netdev. This is already dissimilar to the setup (and error path teardown path) from enetc_pf_probe, but more than that, it is buggy because it is invalid to call phylink_stop after phylink_destroy. So let's first unregister the netdev (and let the .ndo_stop events consume themselves), then destroy the phylink instance, then free the netdev.

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.
