1. Add / remove x25_link_device by NETDEV_REGISTER/UNREGISTER and also by NETDEV_POST_TYPE_CHANGE/NETDEV_PRE_TYPE_CHANGE. This change is needed so that the x25_neigh struct for an interface is already created when it shows up and is kept independently if the interface goes UP or DOWN. This is used in an upcomming commit, where x25 params of an neighbour will get configurable through ioctls. 2. NETDEV_CHANGE event makes it possible to handle carrier loss and detection. If carrier is lost, clean up everything related to this neighbour by calling x25_link_terminated(). 3. Also call x25_link_terminated() for NETDEV_DOWN events and remove the call to x25_clear_forward_by_dev() in x25_route_device_down(), as this is already called by x25_kill_by_neigh() which gets called by x25_link_terminated(). 4. Do nothing for NETDEV_UP and NETDEV_GOING_DOWN events, as these will be handled in layer 2 (LAPB) and layer3 (X.25) will be informed by layer2 when layer2 link is established and layer3 link should be initiated.

README
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.
