Sergey Ryazanov says: ==================== net: WWAN subsystem improvements While working on WWAN netdev creation support, I notice a few things that could be done to make the wwan subsystem more developer and user friendly. This series implements them. The series begins with a WWAN HW simulator designed simplify testing and make the WWAN subsystem available for a wider audience. The next two patches are intended to make the code a bit more clearer. This is followed by a few patches to make the port device naming more user-friendly. The series is finishes with a set of changes that allow the WWAN AT port to be used with terminal emulation software. All changes were tested with the HW simulator that was introduced in this series, as well as with a Huawei E3372 LTE modem (a CDC-NCM device), which I finally found on my desk. ==================== 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.
