wwan_hwsim creates and removes simulated control ports on module loading and unloading. It would be helpful to be able to create/remove devices and ports at run-time to trigger wwan port (un-)register actions without module reloading. Some simulator objects (e.g. ports) do not have the underling device and it is not possible to fully manage the simulator via sysfs. wwan_hsim intend for developers, so implement it as a self-contained debugfs based management interface.

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.
