Up until now RIFs (router interfaces) were created on demand (e.g., when an IP address was added to a netdev). However, sometimes the device needs to be provided with a RIF when one might not be available. For example, adjacency entries that drop packets need to be programmed with an egress RIF despite the RIF not being used to forward packets. Create such a RIF during initialization so that it could be used later on to support blackhole nexthops.

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.
