Allow 'unreachable', 'blackhole' and 'prohibit' route types to be programmed into the device by sending any packet hitting them to the CPU. This is needed so that users will be able to program a default route into the VRF's table, thereby preventing lookup from leaking to other tables. Audit the code paths to make sure we don't rely on the presence of a nexthop netdev, as it doesn't exist for above mentioned route types.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
