Taking inspiration from the drivers/net/can/can327.c driver and at the suggestion of its author Max Staudt, I removed legacy stuff like `SLCAN_MAGIC' and `slcan_devs' resulting in simplification of the code and its maintainability. The use of slcan_devs is derived from a very old kernel, since slip.c is about 30 years old, so today's kernel allows us to remove it. The .hangup() ldisc function, which only called the ldisc .close(), has been removed since the ldisc layer calls .close() in a good place anyway. The old slcanX name has been dropped in order to use the standard canX interface naming. The ioctl SIOCGIFNAME can be used to query the name of the created interface. Furthermore, there are several ways to get stable interfaces names in user space, e.g. udev or systemd-networkd. The `maxdev' module parameter has also been removed.

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.
